If your 9-bolt came with the car, it should have the same brakes (PBRs) that the 10-bolt has.
If the 9-bolt has the Saginaw :barf: brakes, you'd be shooting yourself in the shorts to take the PBRs off the 10-bolt and put that other crap in their place.

Well then you don't have to change ANYTHING; you can just bolt your calipers onto the other rear. They're the same system.

Re: 9 bolt to 10 bolt DISC rears
because the 9 bolt can only get up to 3.70 gears and i need 4.10's for my setup. Also the only thing nicer about the 9 bolt is the bolt on axles and right now my 3.27 3 series 9 bolt posi is wearing and new ones are 800 dollers. Not worth it in my mind my 13 second car isnt going ot break the 10 bolt and it can be made stronger then the 9 bolt.
----------
the 91-92 z28 rear is bare no backing plates or rotors just axles housing posi and gears.

Those details DO matter.
Yeah, well then you need the right backing plates. Not much way around that. As long as the 10-bolt has the small 4-bolt (disc) flanges, it'll all just bolt right up.

Re: 9 bolt to 10 bolt DISC rears
yes i agree with sofa those details do matter lol. I thought u just wanted a 10bolt well idk lol. But now i understand and yes u can build em tough i run one in the low 12's on a z28. Dint know 9bolts only allowed 3.73s then again ive never done research on them never had one. You could try Ebmiller for backing plates he might know somthing hes on the brake board.

could you put these brakes on a drum rear
So is this a disc 10-bolt (small 4-bolt flanges) or a drum 10-bolt (big tall flange with one large hole)?

If they're both disc brake rear ends, yes.
