To start with, I'm assuming you're looking at '13s. Definitely get the 3.73 gears. You may still end up regearing with 35s, but it'll be more tolerable and if you do regear it'll be cheaper (the front housing is different on the 3.21 gears and will have to be replaced). The automatic is awesome. If you get 33s, I'd wait and see how it looks before adding the BB...you might like it. You're going to want new wheels or spacers for better clearance.
