Windshield Rubber?

[spoggy]

I am making the assumption that, at one time, there was a rubber seal between the windshield and the deck. I'm also thinking that there was something that acted as a seal around the center opening. Finally, the visible rubber "seal" that seats in the channel around the windows on the exterior wasn't purposely cut 4" short on every piece. Any ideas where to find new gasketing/seal material for a 1977? Does anyone know if this is a Taylor Made product?
