Do all z-28's come with a posi rear end?I spotted a 90' or 91' at the salvage yard but can't get under the car because it's got no tires on it.It's got a LO3 powertrain,so what would typically be in it for gears?I'm looking into possibly finding it a new home in my 86'coupe.

 

No.

My 84 Z came with an open end diff...

 

Mine had all the performance stuff for the year (1983)... the L69 (5.0 HO) motor, T5 trans, 3.73 gears, etc.


No posi

 

I'd pull the cover to make sure everything looked good anyway,but i'm still glad i asked.I thought limited-slip rearends were part of the Z-28 package.Assume nothing i guess.I also spotted a burned 4th gen TA with a disc brake rear end,but he wants too much money for it and i'd have too many issues to make it work in my car to make it worth it for me.I just want to have both back tires working for me.

 

One of these days ill pull the cover off of my diff, I have a hunch its a limited slip that had a very hard life. Doing burnouts sometimes will smoke both tires hardcore and other times just the one tire will light up.
