need to put a posi unit in my truck. i unfortunitly didnt get to order it from the factory like i wanted to and had to buy one off the lot. and of course with my luck the truck did not come with posi. whats the best route to take and what are some prices. ive shopped around a bit and looked at mostly eaton units.
Users are having good success with the TruTrac posi and if you shop around you can find them for under $400.

Everyone has had good luck with Ron's and I bought mine from Sadler's who was good as well. Can't go wrong with either, IMO.

I run a eaton posi in mine.
You will probably in the long run have better luck by using your own posi. The g80 has been called a grenade for a reason.
