Looking for a Gold Cap

[Michelle]

Hey guys, I'm looking for a gold cap to replace the one my roommate lost when we were moving. I have a 20oz size lamp, bought at Spencer's about 4 years ago. I've looked everywhere, and can't find a thing. Can anyone help me out? If you need me to post pics of it, I will. I'm also looking for a new globe for it, it got cloudy when we moved, but that's easier to come by. Thanks!
