This is what I always used but it looks like they are discontinued. Maybe Classic industries just don't handle them any more.

They were made in the USA by Clark Industries they were the nicest ones I could find at the time.....
I know that Repops made the weatherstrips for Precision at one time but Now I'm not sure.
By their web site it looks like they still make the window kits.
