Excellent, that said maybe you can shed some light on the alignment of the front carrier with the tab and the rear glass carrier with the channel in terms of the pressure exerted on the tab when retracting the rear glass from the vent position. When that carrier is moving to the rear to get the glass to go down flush, are there any gems you can pass along? That seems to me to be the main failure point since it seems like it's really relying on friction to keep the triangle portion of the rear carrier (the part everyone cuts off after they give up and resign to not having the rear glass vent) align with the front carrier. Perhaps you can post some pics/video on how the alignment of those crucial pieces comes into play for a successful repair of these components? TIA if you can.....
