1969 trailing arm shims
we have taken care of the wheel bearings, removed the trailing arms -- There are a bunch of shims where bolted into the frame -- they were all on one side of the arm and loose -- does not look like the original install -- and does not look right because the shims aren't doing anything -- how are they supposed to be installed and what do they do?

The shims set toe-in/toe-out and they should be on both sides of the trailing arm.
If you have the early style (not slotted) shims give serious consideration to going to the later slotted shims and drilling the t/a pocket for the long cotter pin to retain them. The slotted shims speed up the alignment process and don't require removing the t/a mounting bolt to change them. Also use stainless steel shims to eliminate the rusting together factor.
