I fought the seal related door adjustment fight for a long time. My Steele gaskets eventually aged into an acceptable shape with a few summers of Arkansas heat.

Now with the above said, I do recall someone searching for and finding a generic soft seal that was very similar to the factory seal look. According to the poster, it was the Goldilock seal.

Good Luck,
