There's plenty of cool parts on those websites. Or if you wanna build you own I really couldn't tell ya how to get that round shape but 20 to 22 gauge steel would be choice but be careful cutting it. under extreme heat that thin metal can and will warp.. Of with some 18 gauge of 1/4" steel make you some fender skirts... find some old round fenders and wled and build off of that. Be creative!
