Anybody Have a Recommendation for Finding Weatherstripping?

I'm going to start restoring my "new" 1960 Valiant and thought I'd ask you guys if you know where I can order all of the rubber seals, side glass, cat whiskers, windshield gasket in one place? I can find the rubber I need but it is all over the place...one site has the cat whiskers, another site has a windshield gasket, etc. Frankly, I'm getting tired of registering at different parts stores for one part and that is it.
