Hot Rod John. Looking at the info that you have posted, I assume that those part numbers on your chart are for Richmond gears only? I have a factory 4:11 Posi in our 66 Burb, and I want to put in a 3 series set of gears. I see that they list 4:11 gears in both a 4 series and 3 series carrier. From the factory, is it possible to have a 3 series carrier with 4:11 gears? And if so, how do I confirm which I have?
Thank you for your help.
