Steele Rubber Products may still make them. Disclaimer, I wasnt impressed with the ones I got 15+ years ago. Maybe they improved them since then? A few years ago I couldnt take it any more and put NOS strips on my car.
My gripe is the molded end caps. Way too thick and more like foam than rubber that tears if you look at it wrong. With those caps, you have to slam the doors to get them shut. As I said, maybe they've fixed that in the past 15 years.
