Help With wheel tire combo fitment!

With 73+ spindles and rotors those wheels should fit in the front.

If your rear axle is stock A-body 8 3/4 width and the leaf springs are in the stock location they will not fit in the back.

But if the springs are in the stock location the mini-tub is a complete waste, because the springs are the most restrictive part.
well my concern is the fronts and rubbing! with a 18x8.5 and a 245 40 18 or 255 35 18 setup and rubbing! dont think have trouble in the rear got 29 X 13.50-15 LT back there
