The big question is….what axles do you have? If they are the original small bolt pattern axles, the ONLY brake setup that will fit are the 10”x 1 3/4” set that Superbee6 has. To be able to use ANY OTHER brake setup will require aftermarket axles with the large bolt pattern. The A body small bolt axles have a unique offset that only works with the 1 3/4” shoes, and the backing plates for the small bolt brakes are the ONLY backing plates that work with the small bolt axles. Some people will also say that the 7 1/4” small bolt backing plates will work, but they only have 4 holes for the mounting studs, although the 5th hole can be drilled. If you know this already, disregard my post!
