Thanks. I have a further question, then. According to what I've read, the disc rotors were changed on B bodies to 1 piece in 1973. I'm assuming that the rotors I have are the 2 piece if someone could verify this from the photos.
If mine are the 2 piece, and assuming the fellow got them from the same car, then it seems that I have a 70-72 disc brake set-up from an B or E body car.
Does everyone agree with this?
Thanks, Bill
