15x10 fitment on non-tubbed Duster

It might be doable, but you'd have to build the rear housing "into" the wheels. Seems like .75" narrower per side than OEM would be the housing width (1.5" overall because my wheels have .75 more offset than the Keystones.). Not sure if my B/E body rear drum brakes will affect your measurements. Off-hand the biggest concern would seem to be if the welded shoulder of the housing ends might interfere with the outer u-bolts. I also don't know if there are any concerns with Cal-Tracs being used with 3/4" offset spring mounts. (But the red car has them?)

My Dart Sport:
* OEM width 8 3/4" housing
* Mopar offset leaf spring mounts - 1/2"-3/4". (Don't recall actual measurements.)
* Holeshot 15"x10" wheels with an advertised 4 7/8" offset
* Tires are 9"x30" Hoosier radial slicks. Measured section width is approx. 12 3/8"

Inside fender lip was heavily modified as was the little "skirt" on the frame rail for clearance. Shorter tires may not cause a problem, but should be checked. Car is at a shop 1/2 hour away so I can't take any additional measurements at the moment. But here are the best pics I could find that show the fitment.
