basicly waht the title said im lookin at buying another 3rd gen and i want one with posi
(i used search method came up blank)
please help me (im new to this)
lol

 

All Trans Ams, Z28's, and Formulas could have posi's. The base models almost always do not have posi rears.

 

look for all wheel disc brakes

 

anything could have a posi. like kevin said look at the ones more likely to have it but you never know for sure. i wouldn't get hung up on not buying what i wanted based on what was between the two axles, that's easy to change.

 

plus the stock posi's are garbage!

 

alright cool thanks guys
im in the market for an iroc-z, T/A, or Z/28
my firebird right now is a v6 and i want a bigger engine

but thanks for the heads up how easy is it to change a car into posi? dont you have to like change the rear differential and axle?

 

You change the carrier (the part the ring gear is attached to) to a posi one... you will also need a shim kit and some marking paint (some knowhow too) in order to set your gear lash right.
