I'm not sure what a D-52 caliper is but those are usually mid sized GM. There are 2 types, I understand, the earlier mid sized units and the later "metric" units. Since that looks like most of the big brake conversions, that rely on factory parts, I am guessing the earlier mid size. That would include Camaro and Firebird...probably until the 3rd generation Camaro/Firebird were inroduced. Speedway Motors probably has it online so you could verify.
Now what is a D-52?? Is that a pad #?
