anyone know what make these caliper bracket are ? or what fits them I would guess 70s gm....monte carlo or ????
I think your right, If you measure the distance between the holes It should be 5.5 inches for the 1978-88 gm metric calipers
I'm thinking those are for Pre metric Chevelle style calipers. several outfits cut the out and sold the from the mid 70's on and I think they are still available. It's going to be one or the other just get a measurement and go from there.
Go to the parts store. Buy one of each. Return the one not needed. If the core prices are high, go to the pic-a-part and get the core later after you know what you need.
