still having issues getting windows up properly. do the tracks below or the bottom of the chrome frame have any felt or rubber in them. none i have seen do just thought its worth asking.

The lower rear part of the frame has a insert, here's a link to MSA's repro part. The OE Nissan part is also still available at MSA.

The tracks shown in your picture just get grease.
