Whose done it? My rear window quit working and when I tore into it I found all of this. I knew it was bad but over the winter it has deteriored much worse. Might be time to throw a truck gate on it and call it a day. Poor old K5 might meet an earlier death then I previously thought 
Hopefully a buddy still has the spare window I gave him for his burb a few years ago when I parted out the 87 Blazer I had for about 6 months.
The back end it SHOT
Ive got a spare top I kept from that other K5. Thinking about cutting it and trying to fiberglass it back together to make a half cab. Wont use my top all summer pretty soon, but would be nice to have the half cab at least in the winter.

This was a few Blazers ago. I'm sure it could be done.
