Angie's car has a non-original 8.5 inch 10 Bolt under it. It is currently a 2.73 open, so everything inside is junk. How hard is it to make a 8.5 10 bolt strong, and what do I have to do to it? I know that 10 bolts las a long time if they are built right, but what upgrades should I do to make it tough? Should I just cut down the Mopar 8 3/4 that I already have? I know it is very strong. Should I hunt up a Ford 9 inch? Spend even more for a 12 bolt?
