15x10 fitment on non-tubbed Duster

your comment about the U-bolts being close to the housing end; I had parts from a previous purchase where the U-bolts were on the housing end. Previous owner had used models from a 4-wheel drive and opened up the holes on the shock plate to work. Maybe that would help...I believe he had the bolt-in offset hangers and shackles. It's been a while, memory fuzzy.
