Application Note:

These calipers are a standard full size GM caliper used for years on many vehicles (1969-72 Chevelle, 73-77 A-Body, 1969-1981 Camaro, 1977 Caprice, S-10 pickups, etc). They will fit any bracket / spindle designed for the large GM calipers (7” mount width).

Depending on the spindle and rotor size they will not fit in most 14” wheels (nor in 15” drum brake wheels).
