What's the deal with...

See the attached link to see how a stock 65 Dart gas cap was modified to eliminate fuel spillage during turns or parked on hills when the tank is close to full:

The o-ring was purchased at a hardware store in the plumbing section.
The gasket was purchased at NAPA & cut to size.

Before you ask.....the raised gas cap screws with spacers underneath are part of a gas cap locking system......unscrew the top screw holding the filler tube to the rear quarter panel. Then re-install from inside the trunk after installing the gas cap....the raised screw/spacer catch on the screw & prevents rotation. When you need to get the cap off....open the trunk & partially unscrew the top filler tube screw to just clear the gas cap stops.

Hopefully this will keep my original gas cap from wandering off to someone's elses early A body while maintaining the stock appearance.
