In this thread:
http://67-72chevytrucks.com/vboard/s...d.php?t=157539 it states to remove the vent window to remove the door window. I was expecting to do the reverse since I cracked the door glass removing & installing the vent window, specifically at the forward upper corner of the glass. I had to remove the vertical fwd felt too in order to rotate the vent assy enough to remove & install. But then, the glass hits the metal of the channel which is where I got some cracking & chipping. Help?
