Simon-note #6 is key. The number on your gearbox. That is a very late
GB number in your photo. It appears that at some point your car
received a replacement transmission as noted by the Gold Seal paint.
This appears to be a BJ8 box. That would be why it has a nylon bush
and it is working properly.
If someone has swapped out the shift towers on the MKII GB to a BJ8
style, than that also would be an indicator of the nylon bush use. If
its working leave well enough alone is my suggestion, and note
somewhere that you have a later GB, or tower, in an earlier car.
Regards, Hank

Well, this is all very confusing…..
You’ll recall that I started this particular hare running?
1) My car is a MkII BT7.
2) I only removed the stick because I was going to have it rechromed.
No problem with it mechanically, only that its appearance was very
worn.
3) The stick has roll pins and no indication that it ever had
anything different.
4) I knew nothing about differing sticks, but reference to suppliers
websites led me to expect a brass thingie underneath the stick. But, I
found the nylon version.
5) There was no functional reason to replace the stick ie it, with
roll pins and nylon bush, had been in situ during my tenure of 25+/-
years. And for how long before that?? When I had first gear and
reverse looked at by John Chatham’s 25 years ago they may have
removed the stick, but I expect not.
6) The box is a BMC Goldseal which is painted and, on the clutch
bell-housing, tagged AEC 3554 which, I gather from my parts book, is a
MkII gearbox. However, I haven’t looked at the number on the gearbox
cover.
7) When I bought the car, it came with a “box of bits”. Inside
was a bag, marked BJ8, which contained a nylon bush. For years I had
no idea what that was!!
8) When I ordered a bush for my car as the old one had to be at least
25 years old, AH Spares sent me the nylon version. This was identical
to the one from the “box of bits”.
I have to say that I’m flummoxed.
The Goldseal business may imply that there was a run of boxes coming
out of BMC which were a blend of MkII and III. ie roll pins and nylon
bush???
When pondering all this, I remind myself that the nylon bush/roll pin
setup worked for at least 25 years, took me all over the place. Even
over the Alps. And is working now.
If you look at the Ahead4Healeys site, you’ll see that they list a
nylon alternative, GS 4051, for the side-shift brass bush, GS4050, and
that nylon _LOOKS_ exactly like the one they list for the centre
change box. They call this “for BJ8” and make no mention of MkIIs.
Any ideas? I’ll be taking out the tunnel etc when my new carpet kit
arrives but I hate the idea of battling with that spring again.

Lets be careful here. We have others who have been stuck in gear or
without gears. The nylon bush is ONLY USED ON THE BJ8. The brass bush
is used on the MK II gearbox, which INCLUDES THE BJ7. The BJ7 is
actually a MK II Healey. The shift levers are different as well. Here
are the numbers from the parts book:
BJ7 lever AEC8636, Bush-brass AEC 3520 (1 pr.) Circlip 1G3709- this
comes as a set. Roll pins (2) AEA558. Circlip hold two halves of bush
together.
BJ8 lever 22B195-non/OD. Lever AEC3636 w/OD. Lever Bush 22B191
(nylon). Roll Pin AEA558 This arrangement starts with: GB 101-118
wo/OD, 101-1441 w/OD
What will happen if you use the nylon bush in the MKII GB, is that
after a few shifts the nylon will get mangled and there goes your
gears.

MKIII NYLON- DO NOT SUBSTITUTE. Hank

Pretty sure that the only change was the size of the ball upon which
the nylon bush rotates HOWEVER there is a complication ... there are
nylon bushes, from an MGB as I recall, which can be used with the
lever with the smaller ball end.

Hi,
I have a late Mk II BT7. Centre change. So, my query is regarding the
gearstick.
The box is a BMC Goldseal replacement per the attached picture.
The stick has the two roll pins securing it which you’d expect up
to BJ8s which, I gather, had screws. But the bush under the stick in
the white nylon one which, I gather again, started with BJ8s. (To be
fair, I’ve looked into this and didn’t find a definitive answer on
the bushes). My gearbox seems to be a bit of a BT7/BJ8 mixture.
My question is can you put a roll-pin gearstick into a BJ8? Or
vice-verca?
Thanks,
Simon
