also, don't forget to plug the t-case where the old gearbox bolts to it. the new 5th gear is where the old bolt goes, if you get that? yeah, and the oiler cup/nipple thingy too. hands down the best thing I've done so far- lower first, and much quieter as well...there is a detailed how-to on the technical links section of this very sight! it's good, and helped me with my swap.
