I currently have a 8.2 10 bolt with a auburn limited slip differential with 3.73 gears and disk brake kit from perfomance online. I also have a stock ford 9'' with axles and disk brakes out of a lincoln verasailles. I just finished mini tubbing my car and i am comtenplating which rear axle to use? I plan on having a 383 with an estimated 450 hp if i choose to stick with the 10 bolt will it hold up? Im trying not spend a bunch of money, i understand if i build up the 9'' i wont ever have to worry about it. But i already spent a bunch of money on the 10 bolt. Im not trying to start over but if i have to sell the 10 bolt and start over with the 9" i will. Should i just get the 10bolt cut down to fit or just start over tje 9"?
