castle nuts..cotter pins and rear brake plate to rear end are bolted together with copper coated stuff originally on certain assy lines..its corrosion resistant and is assy line...ive taken many orig cars apart and if you clean carefully you can see the copper..i actually found a post somewhere on the 12 bolts in camaros shows the copper nuts on the brake backing plate...i didnt know what to think, and then searched a little and they show up a lot.

i have a bunch that the Leeds workers took home in their pockets or stole or pinched what ever you call it...seems like most assy line guys estate sales have a few of each..

cotter pins are a unique shape and size...i will get a few pics of whats easy to get to.
