Later on 4.11 gears were available for that rear. Those three are your only real options unless you change rears.
Are you also changing the motor? I know at least one guy who swapped rears and ended up with a truck that would no longer move a load. He put 3.42 gears under a 1-ton and was never happy with the result.
Think hard about how you intend to use the truck before deciding which route to take.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
