Best place to buy shoebox window rubber?

Getting ready for glass for the 50 ford tudor i'm building for my wife. Anybody know of a good source for new rubber for the front and rear windows?

 

I got mine from Dennis Carpenter.

 

Shoeboxford.com

 

I used all Carpenter on my 51 Vicky. I did have a few issues but I don't know of any other choices. Seems the other suppliers just mark up and sell Carpenter stuff. Please correct me if I'm wrong. I'm doing a 50 Convert soon and would like other options.

I replaced the back window and rubber on my '50 Coupe. The rubber came from Dennis Carpenter. The fit was good. I've also used rubber from Shoeboxford.com for the hood seal for the radiator air deflector which was from Dennis Carpenter. Use Shoeboxford.com. Chris is a supper nice guy and it is a small buisness. just my 2 cents.
