Need disc brake parts

It does sort of contradict, but it's true you should do as much research as possible because, thankfully there are a lot of write-ups on the subject of early A brakes.
On the note of M body stuff, the only thing that I would use is the rotors or maybe the calipers. The spindles change the geometry toward bump steer way too much.
I'm actually going to use the bigger bearing hubs for drum takes to carry Brembo 13 inch rotors and calipers. I got this set up for a song and I know its still in working order. If anybody has the spindles and LBC hubs for drums I still need them.
