Ford Trucks were the first to come out with a High Back Bucket w/ Square Shoulder seats which were impossible to cover with off-the-shelf seat covers.
These Ford trucks are a large investment to say the least. Many of these trucks were used by farmers who work hard and dirty. They needed to use the same truck to take the family to dinner. This High Back Bucket w/ Square Shoulder, that we call the F-cap, fit these seats like a glove. So easy to slip the cover off when needed to sit on clean seats, throw in back on the next morning for work.
If this describes your situation, act now to get this SeatKeeper seat cover while you can.
