Sorry that this reply is so late, however I just saw it. If your still looking, go to
https://www.steelerubber.com/. I had the same issue and after much research ended up getting samples and catalogs from them (free). They are easy to work with.
You will find out that they only have the seals in black and I'm sure that yours are white. I was hesitant to put the black ones on however you will not notice any diference. They actually look better.
Good Luck
