I love a good RingBrothers build. That would be awesome on your build. I'm doing the LeMans filler, slightly recessed and likely in the middle of the decklid filler panel. I'm 6'6" so I'll be able to reach it from both sides of the car, plus it will be SUPER low and shouldn't be a problem for those on the shorter side to reach. Those on the thicker side could have some issues however. Can't wait to see what you do with this. What is the fuel door (pic 2) off from?
