Flip Top Gas Cap Conversion

Looks pretty good. Did you shave yours?

No. I keep meaning to pull it off the car and take it to a belt sander. But as you can see in the picture, it really doesn't sit at that much of an angle. You'd really only need to take an 1/8" off of it to make it perfect. Also, the one on my Duster is an older one, I think he may have changed them slightly and made the adaptor just a bit thinner.
