Ok, I was doing some investigation this weekend on my Grand Prix.
I have:
7.5" rear with 2.3x?? gears and a POSI unit. I want to keep the posi, but need to change gears to either a 3.50 or 3.73.
Do I need gears specific for a POSI unit? If so, what is all involved and how much $$$ will I have in this rear? It needs sand blasted and probably rebuilt.
The other option is a Ford 9" from QuickPerformance. A buddy has a 3.50 POSI center unit for a Ford 9" that I could get. http://www.quickperformance.com/Products/housings.htm#Axles Anyone with experience from these guys?
