Just food for thought; the Parma 1/8 scale 2004 F150 body is wider and would erase some of the look of the extra width appearance from the tires. It is a bit long for a GP, so when I ran this body, I would cut the body in almost half; just in back of the cab. Leaving the cab/front end and the bed as two separate pieces. Then I'd choose how long the body needed to be, tape the bed and cab into position, and drill holes(2 per side), and bolt the body back together, and paint it. It worked well, and brought the fender wells closer width-wise out to the tires.
