Possibly one that fits down inside the neck and expands?
Go to your favorite auto parts and ask for a stant non-locking vented gas cap for a 67-70. The one I picked up is chrome non-locking and looks original. It has a thick rubber o-ring and is very snug as you twist it on, I no longer have issues with leaks when turning or any pressure buildup. I was using a locking stant cap previously...

good luck.
