I wish I could tell you exactly what to do, but all I can do is tell you what didn't work. I removed the passenger window and took it to a glass shop locally for flexible glass channel (felt) and they sold me some they thought might work, it didn't. I then ordered C.R. LAURENCE 21116181951C CRL 7/16" x 3/8" Universal Channel in a 100 Foot Roll which according to specs should have worked. It almost did. I have the passenger window re-installed, but you need a tool designed to lift glass tp get it to slide.

Lost the engine, so put this project on hold temporarily. My plan is to contact peninsula glass and go with what @Retro used.
