WTS: Unknown locking gas caps

[gen4maxima536]

I've got these two one locking gas caps, i'm not sure what they fit.

Looking for $20/each shipped, but will entertain offers

 

This first one bought on ebay listed for a 510 wagon, but does not fit my early wagon.

First one sold

 

This second one might fit a late wagon, no idea.

I have the first one on my 71 wagon. Kinda a tight fit, but you know it works cuz you can hear 2 clicks.

 

Here it is on my wagon:
