Hello All,
I'm just wanting to know if any one knows what model Oldsmobile these might have been fitted to back in the 60's.
I've taken them off my car as they need rebuilding and I'm having trouble sourcing parts to have them rebuilt.
The correct size springs behind the piston, the correct length securing bolts either end of the caliper are what I can't find.
I have managed to secure the new pistons along with the seal kits and the pads and securing pins and circlips.





These are fitted to my 67 Impala. New from factory.

 

The 67-68 cars used the four piston calipers. A-body cars used 1" thick rotors, full size used 1.25" thick. The calipers do not interchange. The Olds calipers use larger pistons than do the Chevy calipers. Impala brakes do not fit Olds full size. Sell those to a Chevy restorer and get correct Olds parts.
