E-Revonut, I know there's more to it than that. I just wanted to get an idea of where I needed to be pinion wise since I plan to order 3-4 pinions to get the truck going and give myself some options. I just didn't want to order, say a 16-17-18-19 setup and then realize I need a 20-21-22-23 set of pinions to be in the ballpark, those suckers aren't cheap.
