65 Barracuda Filler Neck Solution?

My " Original" 65 B-cuda Gas Cap got a brittle seal and cracked...
I put in a needle in it to show the Crack as you don't see it otherwise... so check yours closely!!! (If you use this type)
My 2nd cap ( made by Stant I believe ) was much better with thicker/ softer gasket... My fall back cap should I remove the Flip Top Cap... ( somehow I doubt that will happen as I really like the Flip Top one )
