This is my truck with All-Pro hanger and shackles, 4" All-Pro springs with the bottom leaf removed, and a 1" body lift above 37" MT/Rs. The truck is pretty much gutted and the springs are not broken in, I hope that it will still be an inch or two lower once it is all dialed in.

Have you considered using axle relocation plates in order to move the axle forward another inch? These will affect your caster angle (for the better) and pinion angle (for the worse) but should solve your clearance problems and be a lot easier.
