3.18, 3.55, 3.92. The available ones were different depending on engine
choices, etc. The ratio is usually indicated by a metal tag on one of
the bolts attaching the differential cover.
Any recent model year with the same rear axle (probably 9 1/4 or 8 3/4)
should work. You'd have to find out for sure what the specs are for
things like the rear wheel speed sensor -- I remember that it changed at
some point (I think before '99), but I can't recall exactly when. If
you've got a 4x4, then you obviously need to match your gear ratios. If
not, this might be a good time to change gear ratios if you're so inclined.
To verify what ratio you have now, check for the tag on the diff cover
and also look for the label inside your glove box. It should indicate
what the factory gears were. (You can do the same if you're looking at
donor trucks at the junkyard, assuming someone hasn't pirated the glove
box already) A dealer can also run the VIN of the vehicle and give you
a report of what came on it when it was new.
