Should be 99 and up through 04 F-250 and F-350 SWR with a pickup box, not a Cab and Chassis SWR F-350.
The wheel pattern is 8x170mm. I think in 05 when they went to the coil front on the 4x4, they also changed the axle width and wheel size due to larger brakes. The wheel is a 17" rim vs a 16" on the 99-04. You can see the difference in width by looking at the wheel, a 99-04 has a bit of "dish" in the center and the 05+ the wheel has almost no "dish", it is almost even with the outside bead.....
