    Default 12 Bolt Upgrade

    Can anyone give me some advice on modifying my differential housing for a 12 bolt. Other than a lot of grinding, what is involved other than gear set up.

    Thanks for info on Tom's--looks like the upgrade parts I am looking for. Still would like comments from someone who has done the work on the differential housing themselves.
