Talk to Eric about ordering some gears. He should be able to hook you up. I got mine installed for 500 just for labor. So I think I had around 1500 in parts and labor. What rear end do you have? You have the 8.8 front reverse rotation. You have either the 8.8 rear or the 9.75. If you have the 8.8 it will be a good deal cheaper than what I paid.
