1964 barracuda windshield gasket

I searched with numerous suppliers. Got the same story from all of them. One company that made them went out of business and the other has them on back order for months.
If you find a source be sure to post it up.
As far as the insert strip, I'm not aware of anyone making a replacement that is correct. The original had a kind of "squiggle design" on it. There are smooth chrome look and black inserts readily available from glass shops.
