idk the sizes just go to the hardware store near ur home, and get a piece of metal that looks good, i seriously dont know the sizes
i just went ito the hardware store and picked up a piece of stele taht was tough but not to heavy looking
Okay here you go.. It's 3/4in. like James said, and it comes in standard sizes like 3, 4 and 6 feet. just get like 6 feet that way you have left over to use later and then you're gonna have to drill the holes and cut them to size and all that shit.
