66 Plymouth Valiant help!

@ J par - I'm sorry, but I don't quite follow the first half of your post. I get the part about the A-Body disc brakes being interchangeable, but I can't quite understand the first half.

@ 66340SEDAN - Hmm. I haven't heard any bad things, so that's promising. It also seems like the rotor has the 5-4.5 bolt pattern drilled into it already as well.
