you currently have.
A 3.73 rear end would have to come from a later vehicle which would require some
spring pad relocation and driveshaft mods. It wouldn't change much from the 3.90
standard gearset in the truck.
There is a 3.38 gear set available for the corporate Eaton that came with the truck.
There are factory overdrives and later units available using the stock rear end.
I believe in disc brake upgrades, there are 6 lug conversions available.
5 lug conversions will require all new wheels and possibly tires.
