I just got off the phone with the Right Stuff Detailing. The front disc conversion kit is a reproduction of that found on a 69' Firebird. This kit bolted right on no issues. The rear disc conversion kit they tell me is not exactly a direct bolt on. The rotors are from a 79' Firebird, the calipers are form a 78-81 Cadillac Eldorado. The issues are that where the rotor fits over the axle, the rotor hole may need to be opened up about 1/16" of an inch to fit over the axle. The other issue is that the OD (outside diameter) of the axle may need to be turned down the fit the rotor. If you call them speak to a gentleman by the name of Bear in the tech dept. Here is there web site.
