Beltline Molding Weatherstrips

Who carries the best beltline weatherstrip for a 68 Barracuda, Steele or Softseal or someone else? these weatherstrips on my car are in mint condition, only if the rubber on these stripes had been just a tiny bit wider then these pieces would be perfect. I just don't like the fact that when my windows are closed the weatherstrips don't hold a uniform consistency right across the glass. Areas of the rubber are sinking here and there as if not wide enough to remain pressed up against the glass, maybe I'm just too particular and that's the problem.
