Need section of weatherstrip (but not the whole kit!)

[CaptainVictory]

All -- I have a 1961 convertible. One section of the top's weatherstripping is messed up and needs to be replaced. Sadly, Concours and Bird's Nest and T-Bird HQ only sell the kits. They don't sell individual pieces.

Anyone know where I can get an individual section of the weatherstrip? This is driving me nuts!
