I need a rearend for my K5 blazer. It had a 10 bolt with 3:73s in it but it broke (to put it nicely). A 12 bolt will work too im assuming as long as it has 3:73s in it. I would prefer another 10 bolt. It doesnt have to be the entire rearend either. I have axles and housing. I just need the ring, pinion, spyder gears. It needs to be a 6 lug too. Email me or post a reply with anything you have.
