Who has Dr. Diff 8 3/4 rear discs?

Thanks @72bluNblu , I don't have any piece of the parking brake installed. That's what has me nervous. Il see what I have.

Oh I see, that does make it more work. But still totally doable with the car assembled. More of a pain, but not impossible by any means.

If DoctorDiff doesn't sell the rest of the parking brake cables and hardware I know inline tube does, I bought the cables for my Challenger from them.
