Check out the install kits at the bottom. The basic kit is the bare minimum. It is strongly recommended to replace the carrier and pinion bearings as well. The complete kit is what you should go with.

Actually after checking over that again, the basic kit is pretty much useless, as it does not include carrier shims. Assuming your setup is stock, you'll have solid 1-piece spacers on each side of the carrier, so you'll need a whole set of shims.

The t/a girdle cover isn't needed unless you're making like 300 RWHP.. *I think that's what someone posted a week or two back, correct me if I'm wrong*
