   I knew the Dnuz had addressed this situation previously, so I looked it =
up. Took some searching (I started at 1990), &nbsp;but I found it in the Fe=
bruary 1980 issue, including a copy of the factory drawing which shows thes=
e plates incorrectly. For those of us in the association in those days, the=
 pages of the Dnuz drip with nostalgia.&nbsp;

   </div> I have recently finished installation of the RATCO cross member t=
hat serves as the rear diff support and the mounting plate for the lever sh=
ocks. The project was long and a bit tedious, but I am very happy with the =
result. However, when I was reassembling the hubs to the aluminum trailing =
arms I found that a couple of the six studs on each TA had stripped the hol=
es or their own threads when the studs came out with the nyloc nuts. I deci=
ded to use the Patton-Machine TARK-KS guide kit for drilling and tapping th=
e trailing arms for Keenserts. That went extremely well, and I now feel con=
fident that the hubs (and wheels!) are securely mounted to the new studs th=
at are in turn secure in the Keenserts.=20

    Today I thought I was going to simply adjust the brakes, so I got out m=
y official shop manual to refresh my memory. Now I feel pretty foolish, so =
I am going to have to ask for help. The diagram of the brake cylinder shim =
sequence in the manual does not agree with the instructions. I am pretty su=
re that the instructions are right and my earlier installation based on the=
 diagram and a Google AI query is wrong, but I would like some corroboratio=
n.&nbsp;=20

     The manual says:
    </div>=20
    <div>
     1) The thin spring(y) shim with 2 tabs at the open end slides into the=
 cylinder's groove first, from the front side (where the hand brake lever i=
s), against the back of the backplate with the tabs pointing out.
    </div>=20
    <div>
     2) The thicker flat locking shim slides in from the opposite direction=
 until the tabs from the spring shim fit into the slots in the locking shim=
.
    </div>=20
    <div>
     3) The shorter flat spacing shim slides in from the front on top of th=
e other shims. Somehow I have misplaced one of these shims--another problem=
 to deal with!&nbsp;
    </div>=20
    <div>
     &nbsp;
    </div>=20

     Is that correct? I had reversed the first two shims.
    </div>=20

     If anyone has an interest in or questions about the the RATCO installa=
tion or the Patton-Machine kit, I would be happy to provide details.
