You will be so much better off if you find a 10 bolt or 12 bolt and rebuild it. They will handle it better and be cheaper in the long run. Trust me, I just switched out my 10 bolt for another 10 bolt that was built. I did it in two days by myself and thats including painting the way bar and brackets.
