I have a body buck with 3- 8" pneumatic harbor freight tires that I think I'm done with. All I want is the $20 I have in the tires. I welded up some scrap angle iron and bolted it to 2 2x8s that are spaced the same as the 2 outer body rails. It makes it easy for one man to move the body in and out of the garage unaided. If there's no interest, I'll make my kid a go cart out of it I guess.
