Hello, I have a 1977 B200 van. The original window felt material is shot. Looking for recommendations on where to purchase new material. I have already tried two sources and the kits they supplied pinch the glass so tight you can not roll the window up/down. Has anyone had this issue ? Where do I get the correct material ?

 

LMC truck? Classic Industries? Rock Auto??

 

I have ordered kits from RA, then LMC. Even though each use different internal part numbers, it is the same exact kit made by a 3rd party manufacturer. The kits have the same 3rd party part #. I'm looking for alternative sources.
