91' rear end?

[allpau2thou]

I can handle swaping the rear axle, it's just swapping out the trac loc Im not sure Im up for. Something I will need to learn at some point but for now trying to keep it as simple a plug and play as possible...

Your best bet in finding a trac-loc rear axle is from a 4wd. Most 4wd's got trac loc rears. As for the larger U joint, adpating that can either be done by swapping the pinion flange or using a combination U-joint. No big deal either way.

Is a rear end with lockers equivalent to a limited slip?

If the driveshaft from the same truck the axle come from I won't have to worry about the u joint correct?

Ford's Traction Loc is a limited slip differential. It uses clutch packs and a heavy spring pushing on the clutches to "lock" the axles together. "Lockers" on the other hand, are usually a ratchet type of differential that positively lock the axles together and unlock when one axle needs to turn faster (as in a turn) than the other. These are the only two style differentials I've seen in Fords, there may be others though I'm not aware of. The Trac-loc differential is the type most often installed in Fords.As for your driveshaft question, that would depend on what transmission and the wheel base of the truck you get the axle from vs what you now have.

It is too big of a difference in joints, I couldn't find an adaptor joint for my 8.8.

I took the flange off and had a machine shop drill and tap another set of holes in it so now I can roll either way. Gotta be carefull with the preloading putting the flange back on though.
