I have a 86 firebird that came with a 9 bolt posi. was worn out and found a cheap 10 bolt from a 85 that had drums on it. swapped out the 2 and afterwards found that the mounting plates for the calipers are different. so looking for a set of those mounting plates for a 10 bolt. thanks for any replies.

 

I've got a complete 10 bolt out of my 84 that I am selliing. Good calipers, rotors, 3.73 gear, LCARB's, and long ARP wheel studs. It does need sides, and spiders. $150.00 plus the ride.

 

would be interested in it. where about in IL are you and how would we work out the drive?

 

I am located near the Peoria area, where in michigan are you located. I would be willing to do some driving if we can work out a deal. Feel free to pm me if you want.
