I know it it not like a 9 inch where you can just swap out center section but I do want to keep it stock as possible.

I'm very happy with the 3.23 I went with. Nice balance of acceleration, highway cruise and traction. Since my original carrier was toast (restoration shop didn't check if for lube before driving), I replaced it with a Yukon posi and 31 spline axles. I went with a RIchmond gear set.
