buy a new 1 from hq?
I ... rigged a horrible one, depending on the type of deck you use and if you rest your foot on it, it might not last a while.
Anyway, i took a pro brake, marked a point where it was above the drop outs on a pro mod, drilled through and bolted so it couldn't touch the wheel.
(poor diagram)
if the bolt is nice and snug against the deck, it works pretty well
i welded them, it does its job and stay super dialed, they look sketchy though
