Plan to run a 8.8" explorer rear which is a direct bolt in. Shock mounts are off but I can modify that. Just need to know what fits pretty much. I'll cut down a f150 8.8" if I need to. Just need to know biggest that fits...

 

cant go wrong with 15x8, 4.5in backspace

 

At stock height I've got 10 3/4" - 11" from frame to wheel lip. Leaf springs stick into this space 1/4". Take away 1/4" inside/outside each for clearance and a 10" sidewall tire will clear. Now if it wasn't so damn cold here to go take a wheel off to measure from the wheel mounting flange to the leaf spring for clearance I could figure out and what to run With a explorer 8.8" rear.
