Rear quarter window issues

I haven't had to adjust mine since I put them.

I will take a swag at how to adjust from memory.

1) take out rear seat.
2) remove side panels
3) remove upper fascia. (piece that the panel is directly under)
4) when all is removed inspect the rollers. (this is a very common reason for misalignment and trouble with the mechanism.)
5) if all seems well then the center bar that holds the regulator has a bolt which allows some adjustment. ( a little movement goes a long way.)

I don't know if it will help but I also have a section in by build below that goes through the installation of the quarter windows.

and yes that chrome piece should have felt on it. the piece clips in and I believe might have a screw towards the door. Any classic car parts place should have them.. I think that I got mine from Dante's Mopar don't remember. The are simply called side glass weatherstripping.

Hope that this helps out in some manner.
