Okay, I got my truck back from having the rear end and brakes done by one company and the front brakes and steering parts done by another. In a box were four sets of nuts, bolts and bracket plates. Neither guy says they removed them or know what they are to. I thought maybe they were from the rear brakes. 1960, C20 Apache manual brakes without emergency brake. Can anyone ID these parts or tell me they are absolutely not from the front or rear end of a 1960 C20.... They may be from a different vehicle that ashop guy tossed on my left over parts pile which I asked them to keep and return.
Almost looks like part of an AD cab mount shackle. However, those shackles have the through bolts permanently attached to the plate. That could be other half? I’d have to go measure my shackles to get a size to see.
