door glass

There are three small screws (front, middle, back) that attach the glass to the regulator. All of mine had to be drilled out due to corrosion/time untouched, so you may want to consider that and have some new ones on hand.
I'm pretty sure you cannot remove it still on the track, it was hard enough off. Lots of tilting and wiggling, and a little profanity, too.
 
That's great news! I was worried about it being gooped in there with glue.
I'm thinking of putting my internals into a repro door and I'm trying to think of what would be involved.
