Had problems with the rear window sticking. Disassembled the rear quarter window hardware and found the center window guide roller was broken. Three questions: 1 - is there a supplier for replacement plastic rollers? 2 - the roller tracks were lubed with lubraplate, which dried up long ago. is there a better lubricant for today, such as synthetic lube? 3 - GM specifies tool J-22055 to remove and replace the roller bolts. Anyone know where to obtain this tool or it's equivalent?
