Hello to all, My wife and I are restoring a 1971 Aljo and need a source for rubber window seals/gaskets. The windows appear to be manufactured by ILC. It's the only marking I can find and the logo is three diamonds with one of letters in each diamond. They are definitely not Hehr windows and I have tried several Hehr seals but none will work. We have tried all of our window supply houses but no one has any information on these windows. Can you help? Thanks.
