Retrofit Help, PBR Disc to drums
I have ruled out rebuilding my brothers 9-bolt and decided to go find a 10 bolt. All the 10 bolts with disc were impossible to find or way to expensive. I do not want to convert to a 4th gen because of spacing issues so I decided to find any old 10 bolt with drums and just beef up the internals for the same cost of buying a rear with disc. Will I notice any differance in stoping power? Those drums look pretty beefy and there really is not that much weight in the back of our cars anyway. Did they make different size drums? Any drums I want to stay away from? Thanks in advance. PS anyone got a beefed up rear end they would let go for around 600?

I don't have a rear that'll work for ya ( I do got a '90 10 bolt 2.73 with aluminum drums but nobody else wants it so why would you) but I want your brother's PBR 9-bolt setup!!! Do I win the auction??? At the very least I need the backing plates that mount the PBR's. Thanks!!! Send me a note or get ready to get one from me...

It was fine for 90K miles - hey for what it mattered the posi even worked - when I took it out to trade it for the 3.27 9 bolt with the old gm disks - I want to put the PBR's on the thing because at the end of it all, GM rear disks SUCK.
I really didn't want any money for it and I don't know why you'd want it myself... 2.73's SUCK too.

I am totally serious, if it has 28 spline axels and the drums work well it will be fine. I would upgrade to a street locker, one of those pressure cap covers and 3.4 aftermarket gears and it would be a hell of a lot stronger then a stock 9-bolt
