Going a different direction with my build, so here's my OBX Cobra style Fuel Door Assembly. It was polished aluminum, but I painted it black to match my Blue/Black themed NB. I fixed it to pop up a little, when you pull the fuel door handle.
I can leave it Black or make it shine again, your choice?
These are pricey ($200+) online.
I'll sell it for $100 plus shipping.
