56 now, want t put in 4 10? It has a 4 series carrier in it with 4:56 gears. I want to put in 4:10s How do I get the correct ring and pinion?
The Summit catalog lists 3 different size GM 10 bolt rears, 7.5, 8.2 and 8.5. I have no idea what size it is, I only know it has the 4:56 gears with a 4 series carrier. I don't know what year GTO it came out of either.
