im really wanting to upgrade my rear end to 3.42s and really not sure where to start. I have 2.14 gears and 7.5 inch ring gear 10 bolt. does anyone know where or who I would go to get the best set up I can get but still wont break my wallet. I thought I could get just a ring gear and pinion. but I heard that I need to get the hole carrier housing. and I would love to make it posi. trac. I just don't want to buy the wrong set up and installation kit and then my car be down for several days.
