I'm building a roof rack with angle iron (a bedframe) and square tube. It will be about 5x6 and 1/2 feet. I/m trying to figure out the best way to mount it. The front will be on the top of the cab and the back will be on the fiberglass top. Just wondering the best/easiest/cheapest way to attach it. Preferably it will be removable and not damage the top beyond repair. Let me know what you guys have done and or what you've seen.
