I saw recently that Steele is reproducing quarter window seals. I've been looking for a pair of these for so long new or used and stumbled upon these. They're $122.60 a pair. I know others here are interested in these too. Forgive me if this topic has been brought up already

I've seen steele selling them on ebay, too
