I have a 99 z28 6spd with ASR. My bearings are going out and the rear is howling. I looked on speed-eng.com and they have complete rebuild kits but one is for a 8.5" 10 bolt and the other is for a 7.5" 10 bolt. Which one do I need? The brand is ratech. Is there any other rebuild kits that you would recommend?
