keyless gas cap?

[seamax]

I'm looking for a keyless gas cap from vortex or pro-tek. I can't find one for the GS500 specifically. Anyone know what other bike model gas cap would fit on a GS so I can get a keyless gas cap for that model instead?

There is nothing new under the Search.  Wasn't that in the Bible?
