Hey there, Weeds. As you know, we can't say "F O R D" on here without disguising it, and I've gotten into the habit of doing the same with other makers' names. The wheels are from D O D G E 3/4 ton, which have the same 8 bolt pattern as GM 3/4 ton.
I doubt that the half-ton D O D G E wheels have the same bolt pattern as half-ton Chevy. But--when I was looking for wheels, I noticed that late model--say in the 2000 and up range--GM trucks also had wheels with a lot of backset, and I suspect they do have the same bolt pattern. I used the D**** wheels because the center design will allow me to use original hubcaps, but if that is not a concern for you the late GM wheels, or one of many aftermarket wheels for late GM, might work well.
You need right at 6" of backset to get the tires under the fenders. If the late GM wheels don't have that much, or if the late 5 bolt pattern is different, or if you want to use original hubcaps, it will be time to talk to Stockton Wheel or another wheel specialist about building some wheels.
