Can I install Duster headliner without removing windshield?

The pros use what looks like surgical tools to place the material on the stakes behind the gasket.
You'll need to get the front center stretch dead on and pin it at the rear view mirror,
Gathering some slack and wrinkles at the front corners is normal wheather the windshield is removed or not. It's mostly hidden by the visorr hangers.
Any way you go at it , its a chore. Cover those rear seat anchors or they will eat your knees.
