47-59 51 5 window dump truck

[woodwright]

There's a 51(ish) 5 window 2 ton(I think) dump truck that's been sitting out in a field here forever. Thought it would be cool for a work truck with that dump bed. 2 speed rear end which I think are 6.13/8.something. has anybody ever taken one of these and put a more modern drivetrain in it and tires big enough to make use of the gears? I thing 42s would work. Can't find any pictures.
