Hi Cannon
I redid a 1953 Chevy 3800 from a dual wheel tilt bed to a step side 9 foot box in the end....here is the link to my photo bucket page that shows how I did mine...we ended up with 4.10 gears out of a 1985 Chevy (full size) Blazer and I added disc brakes to the front axle too...

If I can stumble / fumble through it ...you can too....
