Door Glass Felts

I've located a 1972 dodge dart swinger. It's pretty clean, but it needs a paint job. Anyway I was checking out to see what's available for the weather stripping and I checked with 2 major restoration companies and I couldn't find the window felts ( do I have the correct name for them ). There's nothing listed after 1971,will the one's for a 1970 or a 1971 dart fit a 1972? Is there a company that has them for a '72 dart swinger? Also I don't have any idea of what the car is worth, they are asking 14k, is that to much? As best as I can tell by the photos the quarter panels, wheel wells are good. It's not far from me but we have bad weather coming our way so it might be next week before I can see it. If I can get it cheap enough and the frame rails and truck floor is good I'll buy it. Is there any special area to check for rust as it's a vinyl top car? I have a good friend that will paint it for me, I have to help with disability and prep work and reassembly but I don't mind a bit.
