| 9 bolt posi trade for a ls1 rear end i have a 89 iroc with 9 bolt and disc brakes, the rpo codes state that it is posi and im pretty sure its a 2 series not sure of the ratio sorry. but i am wanting to trade it for a ls1 rear end or a 10 bolt with discs. i can pop the cover off to make sure and take pictures. i would like to do a even trade if anyone is willing. let me know please. i really dont want the 9 bolt becuase i dont have the money to do gears and all that. i just want a 10 bolt with discs cause i can get a spool cheap for those |
