I would like to know what I should look for when I go to buy a traction aid

 

You'll need a 26 spline unit for an 84 rear. The Eaton, clutch style is your best bet if you can afford one. Stay away from the Eaton Gov-Loc and the Powertrax/Richmond No-Slip locker units. If you decide to buy used, get an Auburn 26 spline unit. Keep in mind they're not rebuildable though, so once it's shot, there's no fixing it. A Zexel-Torsen unit from a 98-02 f-body is an excellent choice for a used posi. They don't use clutches, so there's nothing to wear out. The only catch to using one of those is that you'll need a set of 28 spline axles from a 90-92 f-body. The Detroit Truetrac is similar to the Torsens(no clutches), and I think they make those in 26 spline units. They're cheaper to buy than the Eatons.

 

What about the axle out of this??? Along with the aluminum drive shaft, steering box and cat back exhaust, maybe even the rims,

Can you be sure that the rear has your "traction aid?" Prices seem very good.
