u should toss that 12 bolt and get a dana 60 or 70 rear..full floating much stronger and cheap
whats wrong with a 12B? once u do a c clip elim.... what else is the downfall?
im curious to see your spin.
The OP wanted advice and help with swapping the D44 and 12B..
I don't think he asked if he should dump em for 1tons?
