So if my calculations are right the 56mm less the 1.5" (38.1mm) means a +18mm back space 9.5" wheel will keep the tire in the same place. That sound right?
Looking good. Calculations are correct, except the term is "offset", not backspace. What year rear? I have the late model wider rear, 19x10 79mm offset wheel 285 tire. I had 2" spacers on hand, so now +28mm offset. I will have to roll the fender lip slightly, because there is very little clearance to fenders. The bedsides were previously cut for tubs. I'm surprised you got the tire to fit without tubs. On mine, the 285 looks like it would rub the bedside during articulation.

As for the radiator, can you find a way to mount it closer to the support and use the electric fan? That doesn't look like much clearance for a manual fan.
