I need a clear glass shade for my 30+ year old FDR chandelier. i can't find one locally and a couple years ago (I know I should have replaced it sooner) I found one site that might have had one to fit it but now I can't locate the place. So, can anyone suggest where I might look?

The one I found before was called 71/8" clear Williamsburg shade. The problem I am having is the part that sits in the "holder" needs to be about 1/2" high.
