jason, just passing through and i saw your build. Awesome job! you are doing a fantastic job at scratch building. this should be off the hook when you're done. i have a comment or two for you. you're going to spend alot of time on this so, i'm guessing you want really good accuracy. you may want to build you're chassis with different sizes of tubing/ rod. tubing in a real cage runs from 1" up to 1 5/8". not saying bar placement needs to be perfect but, varying the diameters will help with the "look". here's some drawings with some helpful info. hope it helps.
