Chevy & GMC Vans

The 95 G30 I bought has rust in the lower corner by the windshield. I plan on having the windshield removed so I can fix that spot. And I'm sure I'll find more.
Is the windshield a glue in or the rope pull style?
I've read lots of horror stories on incorrect installation and leaking.

Pretty sure they were all glued in by then, looking at the '93 g van FSM it is.
