I'm looking for steel flatbed or stake rack plans because I need to replace the rusted box on my 96 F150. I know a lot of these are built by eye right on the truck, but I'd like to fabricate one in my shop and then install it.
Any ideas or pointers would be appreciated.

 

i dont have plans, but heres the one we put on my buddies truck last summer, its completely out of square because it was built to look good on the truck
