Ideas needed for frame swap.

[lazerstrouts]

this is a front, rear, and side view of my 48 gmc short box on a 2000-2001 chevy tahoe 4wd chassis at stock ride height. i raised the box 5 inches because i didnt want to cut out the bed floor for the rear upper shock mounts. tires are 235/55/17s on 2008-up spares/cop truck wheels. i still need to do alot of work like running boards and cut the front frame horns off to get the grille in. attery mount is a temporary.
