rear disc brakes on 8 3/4

I'm sure there are reliable sources for "very slightly used" car parts of all varieties available here. I've seen new parts of all descriptions taken out of the box, inadvertently smudged with a bit of grease while being looked at and used for various things, repackaged and shipped as used parts. O:)

I have Dr Diff's rear brakes on both my A-Body and E-Body. They are simple, effective and perform excellent. Best to get big bolt pattern while you are at it.
