They are at a nice price. But if those are Bullnose era Ford wheels, which were used on the 1980 & '81 F100's, F150's, and U150's, they are only 6" wide, not 8.5" as the seller says. At least according to Ford's master parts catalog and shown here: Driveline/
Wheels.
However, it is possible that they are later Ford wheels and are wider. I have a set of Ford wagonwheels (Type 5's) that are wider than the catalog says they should be and I assume they are from a later truck. I know that Ford used them at least through 1989 and by then they were available in 7" and 8" widths, as opposed to the 6" & 7" widths in the Bullnose era.
