Removing front windshield and back glass

Dan,
As far as installing the new headliner, yes I would pull the glass for a better fit. I was going to attempt to leave mine in, but after looking at things, figured I should pull it now and just work on everything at the same time. By looking at it, the gasket blocks quite a bit of where you would install the headliner and to get that tight fit, I'd remove it. As for the front windshield, is it cracked? or does it just need a good cleaning? You would be surprised what some fine steel wool with wax will do to glass...

Also since mine are out, I am going to have the back glass limo tinted and the front faded..should be a good look on all black car..
