Anyone have any experience with them?
My new project is a '71 Fiat 850 Berlina.
Here in the US at least the quarter window rubbers are not avaliable at any source. The rubber is deteriorating and the lock strips are crumbling. the rear seal is still avaliable at one supplier at damn near $200.
My thoughts immediatley turned to the universal seals I remember from decades ago in the JC Whitney catalog. Has anyone used them and can give me an idea whether they are worth my time? googling has turned up nothing.

Thank you
