Yeah it sort of a catch-22. I have to make sure th at the wheels center in both the front and rear. So it going to be juggling everything around to get everything to match up. But the bed is going to be sitting the highest, so I have to mount the cab on blocks and changing the height of the cab until I get it proportionate to the bed.
My two major fabrication projects are going to be the steering gear and radiator support mount.
