Can I assume these to be the full door windows?
Most of the time, you have to remove the felt around the outer window channel in the window door frame. The window should fit within 1/8-1/4" of the window opening in the door. The felt fills this cavity as well as aligns the window when you go up/down. Not sure if the top pulls outward or inward when you lift up to pull the window glass all the way out.
But why do all this when the tint will be along the window edge of the felt? You will have the space from the felt on top of the window but that is really nothing. The tint is added to the window pane while still in the door. Its 'watered' on, pressed to clean out air bubbles, let to dry, and cut to fit to the felt.
