would like to find a 373 posi rearend

should i junkyard one from another f-body

how much to buy new ring&pinion plus posi unit? labor cost at shop?

thanks

 

Eaton posi is $427, installation kit is $100 and gears are about $200. Labor runs around $250.

 

Some of the 4th gens had it with disc brakes. I have a 91 z28 vert that the previous owner put one in. It's pretty much a direct bolt in, the parking brake cables are different though between a 3rd and 4th gen. The only thing that will happen if you get one is the rear end on a 4th gen is about 2 inches wider, so each tire will stick about bout an inch or so more than a stock 3rd gen rear. On my car, it puts the outer edge of the tire pretty much right in line with the outer edge of the quarter panel. I like it, it isn't bad.

 

I have my used set of richmond gears for the 10 bolt. they are 3.73. I will sell to you. Let me know if your interested.
