I've got new weatherstripping (front, back, and bottom) for the rear quarter windows. I'd also like to POR/paint the drip trays at the bottom. I found three large slotted bolt heads on the interior side of the B pillar. Does this mean the quarter window is removable for weatherstrip replacement (and cleaning!)? Any suggestions/warnings/guidance appreciated.

During the drying time for the various coatings, I'm going to clean up all the under dash electrical contacts, and if time allows, the new dash gets fitted today. Too rainy for yard work (yay!).

Thanks

Neil
