I made mine out of a rectangular aluminum tube I ordered from a shop in town. I have a Greddy 3 Row, and Top Secret front skirt, so the oem bar was removed and it wouldn't have fit back.
I still have enough alumium rectangular tube to make 2 bar that fit aftermarket front skirt or I can order the larger oem size tube and make one. Having my dimensions and holes placement from my unit.
Contact me in pm if interested.
