I'm thinking of getting a Ford 9inch with 4.10's 35 spline with a detroit locker. Trying to bulletproof the drivetrain. I have a 12 bolt now. Just with all the reported breakings of the 12 bolts makes me think why I didn't go with the 9inch in the 1st place.
I'm thinking seriously of a Currie built w/ their 9+ parts if I break the 10 bolt. Only problem I see for me is the shipping cost to get it 3/4 the way across the country. Certainly not an issue for you tho.
