After too many bad experiences with lousy fitting repro seals, I only buy OEM seals. I get a very good price at Sunset Imports (Porsche Dealer). Call 1-800-346-0182, ask for Porsche Parts. Ask for Jeff and tell him you want the same price as I get.
No affiliation, just a happy customer. Jeff is a very helpful guy.
For the concours restorer there is no substitute for the factory weatherstrip seals. However the factory molds are getting worse and the repro molds getting better (depending on what source you are using) The factory is also discontinuing the seals left and right, to where one HAS to depend on the repros (unfortunately or fortunately).
An example of inferior factory seals, is the discontinued windshield top seal: In the final years it was available, (914 563 039 10) it was made too short and would not seal correctly, even to the point of splitting when installing!
The after market seals provide a cheap alternative to the expensive factory parts and are good enough, in my opinon, for most driver applications.
