Re: Bullet proof GM 12 bolt.
I would think a Detroit locker, alloy axles and C-clip eliminators and you should be fine. There's really no need to change to a 9 inch IMO. You can get the same upgrade parts for the truck 12 bolt.
You might see if a mod will move this to the 'Racing and High Performance' section. There are a few guys over there running the truck 12 bolts, and they can give you an answer based on real world experience.
