Rear quarter window issues

OK that helps. The window does not move inward easily, at least at the back. The front portion seems a little clanky and loose but it sounds like I need to find the adjustment screws or whatever and see if I can't get the glass to come inward more at the back and tighten it up at the front. I'm sure none of the parts are in stellar shape either so planning on some parts replacements. I'll check out Dante's for the glass weatherstripping. I don't have a manual or anything so I'm definitely struggling with the correct terminology to find some of these parts. Thanks guys!

VDART, if I get stuck along the way, I may take you up on that manual.
