Best gas cap

OK HELLPPPP.I have a 1967 chevy c10 truck steel bed that I converted gas tank under the bed.So whats the best gas cap to put on the bed because of the rails.TTTHHHAAANNNKKSSSS

I've been thinking the same thing but my mechanics are a little apprehensive doing the install. So...it sits in a box until I can either find someone else or get some help myself. That said, I've seen the motorcycle push & pop gas caps and they're clean but look a little weird and personally, I always liked the more flush look w the rivets around the cap is more appealing to me. However, I'm not sure without doing some body work you could make that fit flush with all the groves in the bed unless it's a wood bed?

I hope u get some good feedback on this post cause I too would love to see how others are making it work.
Good luck!
