What do you want to do with the truck? Will it be a street machine, drag race, off road? There are many differentials for that rear end, and getting the best one for the job depends on what you want to do with it. If you use 3.73 gears then you will need a 4 series. The 12 bolt has 30 spline axles stock, but you can upgrade to after market 33 spline axles with the right combination of parts.
