   Well, you have them in the right position, but my order of assembly differs. Position the wheel cylinder on the backing plate. Install the top and bottom plates. Install the handbrake lever.

    Today I thought I was going to simply adjust the brakes, so I got out my 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 sure 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 corroboration.&nbsp; 
    <div>
     &nbsp;
    </div> 
    <div>
     The manual says:
    </div> 
    <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 is), against the back of the backplate with the tabs pointing out.
    </div> 
    <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> 
    <div>
     3) The shorter flat spacing shim slides in from the front on top of the other shims. Somehow I have misplaced one of these shims--another problem to deal with!&nbsp;
    </div> 
    <div>
     &nbsp;
    </div> 
    <div>
     Is that correct? I had reversed the first two shims.

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

That makes a lot of sense! Is that procedure widely known? I sure 
haven't come across it.
Thanks Ed.
