Flip-Top Gas Cap Seals

I had JW133489 make me the ones that fit the '66 and earlier A-body factory cap. Maybe the same seal for the '67-70? They fit and work perfect. Just make sure your filler neck is undamaged. I've run across many of them that were modified to fit the later caps, and that modification (making the hole bigger) ruined them for returning them back to the original cap. Usually the stops get bent and the factory cap will just spin around, or, just catch on one side. These new seals will make your cap fit very tight. If the hole is damaged too much, I doubt the cap will hold on and seal properly.
