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.

I wonder if it came down to putting a larger radius U-bolt on the outboard end if the offset would put the tire into the leaf. The 15x10 Keystone's only come in a 4.125" backspace. The 15x8's come in a 3.875 backspace and I would be running the same 275 tire so the same limitations are there as a 275 on a 10" wheel, I'm sure. May as well go for the 15x10 and custom length housing.

Is the next thing to do just to pull the trigger and buy a 15x10 and a 275? If it goes well I would see if a 295 would work when the 275's wear out.
