I am replacing the pinion seal in my 2001 Z28, M6 and decided to yank the cover to make sure there is nothing wrong with the internals. I just bought the car and wasnt sure how long it was run with low gear oil, or if they just filled it up frequently, or added the limited slip additive. Better to be safe then sorry. Just figured while I was in there I would see which rear end I have. I just dont know the differences. Thanks.

I have an 01 and it came with the Zexel.............if you have the cover off you will be able to see the worm gears ect.........
