I actually picked up a set from a Rail truck (pickups that can run on the rail lines) anyway, it was pretty easy to make them work. They were for an older ford so the bolt patern was the same. Just had to knock out the studs, chuck it in the lathe and bore out the center to fit my hub on my rear axle. I was going to order a set from Preformance wheel but just stumbled across these for free so I went for it. They were 2" thick but I machined them down to 1.5" since I was only going to be running my 255/85r16's
