I have a 39 Ford Standard Sedan Delivery. I need a back window and the weather stripping around the window. Does anyone know if a 39 Standard and a 40 Sedan Delivery are close enough to make the Weather strip fit a 39 Standard. I have the metal trim for the back window, so all I need is a weather seal and a glass, I can get a glass made. No one that sells the 40 and 41 back weather stripping will say if it could be made to work. Has anyone done this or how did they do it. I hope this is the right place to post the question.
