And the newly relocated filler cap will be a one-off piece created from a Ceriani Steering damper, and a weld in filler cap from Lowbrow Customs. Hacked up the damper so that I ended up with just the top knob portion that I wanted. Had to turn down the aluminum Lowbrow filler cap to allow for the damper knob to be pressed in over the outside. Heated up the damper knob and chilled the filler cap, just before marrying the two together. A little green loctite and voila; there to stay.
