i got all the parts (differential, gears, gaskets, bearings, etc.) and was wondering how much to expect to pay to get it installed. what do u guys think?>

 

I saw the local papaer (recycler) had $400. That was all for GM gears with labor. But GM gears are limited by which carrier you have. Aftermarket gears have been made that don't have those limitations. That might be a bit more. You could look for a 3.42 whole rear axle from another car for very cheap.

 

400 to 500 if you want it done right by a reputable rear guy in your area.........ask around........i bought all my parts from
http://www.reiderracing.com/ .i gave em my zip code and they told me where to go........3 years no probs so far.give em a call

 

I paid about $250 for my install.

 

i just wrote the check today. 87 bux. the guy installed the gears posi and shimmed it up and changed out my axle bearings. i had the install kit gears and posi. i had to pull the rearend and give it to him then put it back on but that is no big deal. i didnt even have to mess with the brakes. in fact i am about 50% done putting it back in

 

I just priced it out a couple days ago. I was told $233, that was Labor, it included installing the gears and the posi unit.

 

i talked to a friend of my uncle's who has a repair shop... he told me he's install a diff/gears for 85 bucks with the axle still on the car. i think im gonna go that route
