I'm planning on getting a 350 or LS1 motor to install in the RS they will fit in perfectly but I need to get ready for it and first step is new rear end, lol I'm not going to put all that hp and torque to 1 wheel!

And thanks Turace for the info, I got a guy thats going to hook me up with cleaning/rebuilding if need be, just hope it doesnt come to that.
