From my obsessive leak checking... I had similar that were not the glass. The flange was rotted right under my cowl drains so water came out of the cowl and right back in, down the inside of both sides in kick panel area. Wiper pivots leaked through the center before I added grease zerks. Firewal flange was pinch/spot welded with seam sealer in it. Had some of that come out. I used a good bit of Blackjack Neoprene roof sealer and the butyl rope seal from the window to seal hard to get spots. The back- Had water coming in the quarter glass, and from the single screw that hols the canopy vinyl trim -down the back of the wheelwell humps into the trunk- looked like it was back glass
