Replacement gas cap for 82 GS1100GK?

[stanzukowski]

Lost the gas cap for my 82 GS1100GK. Spent half an hour along the road trying to find it in the weeds. All I got for my efforts was three ticks.

Except Partsnmore is out of stock. Any ideas of where to find a replacement? At this point, I'd settle for anything, doesn't need to be the exact same as long as it fits.

Thanks for any help!

I've seen them anywhere from $24.00 knock offs to $85.00 for the factory part. That cap is the same style as my '79 GS1000E. I'm looking for a replacement rubber seal. I got a lap full of gas yesterday under hard acceleration. I bent the spring steel under the rubber down so it's getting compression now, but there is a ridge worn in the rubber, so this is just a temporary fix.

I've got a cap for a GL but I'm not sure of the year. Either '82 or '83. The Alpha sports fiche shows the '82 GK and GL are interchangeable. Doesn't show the '83 as same part #. Also, it doesn't have a key but keys can be had on Ebay.
