fuel filler cap ideas...

[canadian broco]

I have a 74 single tank model and will be replacing the filler cap (current one is pitted badly).
I notice that some of the vendors sell stock style as well as a billet aluminum one (that says FUEL).
Has anyone here come up with other suitable options?

This a lil diff! Its aluminum from a boat could be used on outside if ya wated.
