i know this is old. but i fabricated new ones (they look pretty dang good tbh but don't have to be perfect as the sideskirts cover them). I had access to a fairly wide sheetmetal brake, but i still had to make each one in to pieces and then weld them together so they'd be long enough. Fabrication isn't all that hard. just need a little bit of know how... hardest part is having access to the tools that make it easy
