Posi Question
What would I have to do to convert my 3.42 open diff to a 4.11 posi?
I don't want to put a 4th gen rear if I don't have to...

Re: Posi Question
Posi unit $400+-, Gears $200+-, Pinion Shims $25+-. IMO 3.42s are the perfect gear for these cars unless you have an all out drag car.

Re: Posi Question
There is a good one on this sight in the stickys. Quick Performance can fix you up with all of the parts that you need in a complete kit with the Yukon Dura Grip, USA Standard installation kit and US Strange gears.

Re: Posi Question
Here's what I did.
With this upgrade the car preforms soooo much better. It like driving a different car.
I have been pushing it pretty hard and its holding up really well for a "have a lot of fun" street car.
Love the 3.42's
