Flip top cap on a dart

okay, I'm really considering this and want to know what you all think. I'm waivering about closing up the factory gas cap location and mounting a flip top cap on top of the quarter ala charger. Keep it simple or make it mine??? It's a 67 gt slant six car but a damn nice one that's being prepped for paint. It's got dutra duals, super six, BBP discs and rear from a 73 duster. Not factory correct or an asphalt eater but a nice fun driver. I would rebend the filler tube. I don't want to put in the whole "bowl" and trim ring on but just flush mount it. The slanted back of the cap actually levels out with the quarter panel. Aside from the work involved and possible paint damage from over spill what do you think??
