Rear end is pretty much the same.  Housing is a little different, but still 8.5" ring 10 bolts.  They use the same gear sets. The carrier and bearings are a little different, but that's it.  Think they still use the NP246 transfer case as the 98-99 OBS trucks.  5.3 isn't a bad motor at all, but they are kinda gutless factory unless you rev them pretty good.</p></blockquote><p></p>
