Dave, I did check the Coil-Over kit, but it looked as if the job would be a=

 with my "fix" to the problem. I did carry it over to "The Triumph Experien=
ce" where I got some more recommendations, and though I was discouraged for=
 a time, I am now very optimistic about my choices.
First, I got out the lever shocks that I had removed a couple of decades ag=

" site (so many great Triumph jobs there) that showed how to refurbish them=
. I did what he did and got a similar result where much more force was need=
ed to move the levers. I really think they are going to work as is, but if =
not I'll get them done by one of the shops mentioned by others here.
Second, I did embark on an attempt to weld up and patch the cracks that had=
 appeared on the left side of the cross member (gas tank out of course). I =
thought I could hold the pieces together with C-clamps and then spot weld t=
hem in a few places from underneath, up into the channel. The idea was to t=
hen add more to the welds in the channel and then weld patches to the outer=
 surfaces of the channel that I would cut from 14 gauge sheet steel. I did =
get a couple of spot welds done, but the channel is narrow, the MIG nozzle =
is pretty wide, and it was very hard to see anything when the nozzle and my=
 hand blocked the light. The killer was my discovery of another crack farth=
er up near the differential that was in an even narrower spot. I called a l=
ocal welder who was happy to come take a look at the possibility of doing a=
 stick weld up there, but he said there was no way it could be done, and he=
 thought the cracking would spread anyway. Total discouragement at that poi=
nt because I just couldn't imagine incurring the expense of a frame-off job=
 to install the RATCO Differential Tower replacement after post-Helene clea=
ring and tree work had depleted our accounts.
A very helpful post on The Triumph Experience (from Ken D) let me know that=
 the RATCO replacement could be done without removing the frame. "Read the =
instructions on the RATCO site," he said. I did, and the process sounded ve=
ry doable, even for this 78 year old. I talked to Bob at RATCO, and got som=
e good advice about carefully checking my frame for rust before proceeding.=
 The cross member set up for lever shocks was not in stock, but it is likel=
y to be shipped next week. Meanwhile I have been busy following the instruc=
tions. I'll briefly describe how things have gone for those who might be th=
inking of the same solution.
There was some initial frame prep required that would be very difficult to =
do without first making room by removing the hubs and half axles from the t=
railing arms and letting the arms hang lower. Each side has 6 nyloc nuts ho=
lding the hub to the cast aluminum trailing arm. All but one of mine came o=
ut nicely, but one nut was frozen to its stud, and that stud and nut unit r=
e-tightened after several turns out. It was extremely tight and I feared st=
ripping the aluminum threads in the arm by forcing it out. It took several =
hours (over a couple of days) of spraying Liquid Wrench, turning back in an=
d then out, tapping the surrounding metal, applying heat with a heat gun (a=
 torch might have been too much for the aluminum) to loosen the nut. It see=
med interminable, but I did begin to feel that the nut was backing out a li=
ttle farther on the stud, and it did finally give leaving the stud and arm =
threads intact. Whew. Another Yakov video showed how to simply pull out the=
 hubs (no need to do anything with the diff). Mine were stuck, but I borrow=
ed a hub puller with a slide hammer from Advance Auto (payed $175, got it r=
efunded after pulling the hubs in 90 min).=C2=A0
I used my little air compression driven grinder with cutting wheel to slice=
 the shock bump stops from the frame sides (to be re-welded later to a fram=
e collar in the RATCO kit). It was a tedious job. I borrowed a friend's Mak=
ita electric angle grinder with a 4.5" diameter, .040" thick cutting wheel =
for the cuts to the old cross member. The cuts on the front side of the old=
 cross member to separate it from the frame were about 6" long and took les=
s than a minute each! The same cuts on the back side of the old cross were =
hindered by the bottom of the trunk area where the gas tank resides. Only a=
bout an inch of the cutting wheel could cut until the body of the angle gri=
nder was blocked from moving farther in. This was incredibly discouraging, =
and I think it is the only flaw in the instructions provided by RATCO. Mayb=
e there are low profile angle grinders that could work? I finally hit on th=
e idea using my saws-all with a good long Diablo metal-cutting blade (I do =
have a few of my own tools at hand). It did a good job of cutting the rest =
of the way and took only a few minutes. I have used a grinding wheel to smo=
oth out the metal left on the frame after some of the cuts, and that has go=
ne well.
Yesterday I reinstalled the hubs using just 2 new nyloc nuts on each. The h=
ardest part (not really bad) was sliding the new rubber boots (old ones wor=
n) over the splines in the shafts before pushing them through the trailing =
arms (held up with a scrap piece of wood). This next is the best thing abou=
t the whole job. Tomorrow I plan to place a jack under the diff, remove the=
 4 nuts holding it to the mounts (2 in the old cross), and then lowering th=
e jack to allow the diff to settle into a cradle of the 2 axles and the dri=
ve shaft. The only thing left holding the old cross in place is an easily a=
ccessed half inch weld on each frame rail. Should take about a minute to cu=
t through those and then pull out the old cross. There will be more grindin=
g to smooth the frame surface in preparation for the new cross member. That=
 cross will be positioned by slowly jacking the diff back up into the 2 sta=
tionary forward mounts and into the mounts on the temporarily movable new c=
ross. Ingenious! At that point my nearby pro welder has agreed to do the we=
lding to the frame.
The current price tag on the RATCO kit is $375 plus shipping. The welder ch=
arges by the hour, but I don't think it should take too long. Maybe $200 or=
 so there; certainly less than $800 total for the fix. That is more than I =
thought it would take originally, but this is much better than having an if=
fy patch job or a car that sits in the garage until . . . ?

I have been hearing a slapping sound either under or behind me in the 1974 =
TR6 when I encounter even slightly rough pavement, so today I decided to so=
rt it out. I thought I had found the problem quickly when I saw that the sp=
are tire securing hook bolt had come loose, but no such luck. When I finall=
y gave up on simple fixes and jacked up the left rear end and removed the t=
ire, I saw that the cross member had cracked near where the after market sh=
ock mount adaptor bolts on. I did a quick check with the Moss parts catalog=
 and that cross member is not available with them. So, I'm wondering if thi=
s shock mount replacement for the old lever shock (I installed a couple of =
decades ago) was a bad idea and put too much pressure on that frame member.=
 It occurs to me that there may be some folks out there who have gone throu=
gh this and can tell me just how a fix should be attempted.
=20
 =C2=A0

That crack shown in the photo seems to be only on the back side of the cros=
s member. I have learned some welding skills in the last few years, and I h=
ave a mig welder, but I have never done anything under a car. I really don'=
t like the proximity of the gas tank either. I am thinking that my local pr=
o welder would be the guy to call on, but is this really something that can=
 be fixed that way?

ructions on the RATCO site," he said. I did, and the process sounded very d=
oable, even for this 78 year old. I talked to Bob at RATCO, and got some go=
od advice about carefully checking my frame for rust before proceeding. The=
 cross member set up for lever shocks was not in stock, but it is likely to=
 be shipped next week. Meanwhile I have been busy following the instruction=
s. I'll briefly describe how things have gone for those who might be thinki=
ng of the same solution.</div><div><br clear=3D"none"></div><div>There was =
some initial frame prep required that would be very difficult to do without=
 first making room by removing the hubs and half axles from the trailing ar=
ms and letting the arms hang lower. Each side has 6 nyloc nuts holding the =
hub to the cast aluminum trailing arm. All but one of mine came out nicely,=
 but one nut was frozen to its stud, and that stud and nut unit re-tightene=
d after several turns out. It was extremely tight and I feared stripping th=
e aluminum threads in the arm by forcing it out. It took several hours (ove=
r a couple of days) of spraying Liquid Wrench, turning back in and then out=
, tapping the surrounding metal, applying heat with a heat gun (a torch mig=
ht have been too much for the aluminum) to loosen the nut. It seemed interm=
inable, but I did begin to feel that the nut was backing out a little farth=
er on the stud, and it did finally give leaving the stud and arm threads in=
tact. Whew. Another Yakov video showed how to simply pull out the hubs (no =
need to do anything with the diff). Mine were stuck, but I borrowed a hub p=
uller with a slide hammer from Advance Auto (payed $175, got it refunded af=
ter pulling the hubs in 90 min).&nbsp;</div><div><br clear=3D"none"></div><=
div>I used my little air compression driven grinder with cutting wheel to s=
lice the shock bump stops from the frame sides (to be re-welded later to a =
frame collar in the RATCO kit). It was a tedious job. I borrowed a friend's=
 Makita electric angle grinder with a 4.5" diameter, .040" thick cutting wh=
eel for the cuts to the old cross member. The cuts on the front side of the=
 old cross member to separate it from the frame were about 6" long and took=
 less than a minute each! The same cuts on the back side of the old cross w=
ere hindered by the bottom of the trunk area where the gas tank resides. On=
ly about an inch of the cutting wheel could cut until the body of the angle=
 grinder was blocked from moving farther in. This was incredibly discouragi=
ng, and I think it is the only flaw in the instructions provided by RATCO. =
Maybe there are low profile angle grinders that could work? I finally hit o=
n the idea using my saws-all with a good long Diablo metal-cutting blade (I=
 do have a few of my own tools at hand). It did a good job of cutting the r=
est of the way and took only a few minutes. I have used a grinding wheel to=
 smooth out the metal left on the frame after some of the cuts, and that ha=
s gone well.</div><div><br clear=3D"none"></div><div>Yesterday I reinstalle=
d the hubs using just 2 new nyloc nuts on each. The hardest part (not reall=
y bad) was sliding the new rubber boots (old ones worn) over the splines in=
 the shafts before pushing them through the trailing arms (held up with a s=
crap piece of wood). This next is the best thing about the whole job. Tomor=
row I plan to place a jack under the diff, remove the 4 nuts holding it to =
the mounts (2 in the old cross), and then lowering the jack to allow the di=
ff to settle into a cradle of the 2 axles and the drive shaft. The only thi=
ng left holding the old cross in place is an easily accessed half inch weld=
 on each frame rail. Should take about a minute to cut through those and th=
en pull out the old cross. There will be more grinding to smooth the frame =
surface in preparation for the new cross member. That cross will be positio=
ned by slowly jacking the diff back up into the 2 stationary forward mounts=
 and into the mounts on the temporarily movable new cross. Ingenious! At th=
at point my nearby pro welder has agreed to do the welding to the frame.</d=
iv><div><br clear=3D"none"></div><div>The current price tag on the RATCO ki=
t is $375 plus shipping. The welder charges by the hour, but I don't think =
it should take too long. Maybe $200 or so there; certainly less than $800 t=
otal for the fix. That is more than I thought it would take originally, but=
 this is much better than having an iffy patch job or a car that sits in th=
e garage until . . . ?</div><div><br clear=3D"none"></div><div>Tim&nbsp;&nb=

n style=3D"font-family:sans-serif;">I have been hearing a slapping sound ei=
ther under or behind me in the 1974 TR6 when I encounter even slightly roug=
h pavement, so today I decided to sort it out. I thought I had found the pr=
oblem
 quickly when I saw that the spare tire securing hook bolt had come loose, =
but no such luck. When I finally gave up on simple fixes and jacked up the =
left rear end and removed the tire, I saw that the cross member had cracked=
 near where the after market shock
 mount adaptor bolts on. I did a quick check with the Moss parts catalog an=
d that cross member is not available with them. So, I'm wondering if this s=
hock mount replacement for the old lever shock (I installed a couple of dec=
ades ago) was a bad idea and put
 too much pressure on that frame member. It occurs to me that there may be =
some folks out there who have gone through this and can tell me just how a =
fix should be attempted.

 anything under a car. I really don't like the proximity of the gas tank ei=
