12 bolt Rear End guts
I got a 12 bolt rear end I am using to convert my 8 lug 3/4 ton.
And would like to know what I need to make it strong enough to handle 450hp and still have good street manners. Gearing might be changed to either 3.73 or 4.11:1 while making the swap. Just need to know if I can put some kind of posi or other unit back there while doing so. THanks.
