Hey everyone! I am doing a little restoration project on a 84 Fila Thunderbird, and have found pretty much all of the replacement parts I need... With one exception. Window run channels. Mine literally fell to pieces when I tried to remove them. Can anyone tell me where to get new ones? Ford does not carry them any more, and all of the aftermarket replacements I can find are the wrong profile. I have posted below a photo of the cross-section.
