So I bought a frame off of a 55 chevy truck that has a 1970 chevelle front sub frame welded in and a 1970 camaro rearend installed and ready to go. So I ordered a new cab to frame mount kit but not sure which bushings go where bc the original bushings were pretty much non existent. The kit came with 2 round bushings, 2 square bushings, 2 small metal sleeves that slide inside the square bushings, 2 large and 2 small metal washers and 2 rubber and 2 metal shims and 2 large and 2 small bolts. My question is do the square bushings going in the front or back of the cab, etc? Any help is greatly appreciated.
