Convertible Canvas Help

92 Ford Mustang Convertible LX. Do I have to unzip the glass on the back before retracting the canvas? Or can I leave the canvas zipped, and will it fall into it's place?

Thanks for any help.

it will fall right in place. congratulations on getting a canvas top, way way better.

i like to unzip the rear window on the highway with the windows down, i feel like there is less turbulence in the cabin and often I leave the window down when i raise and lower the top.

yes unzip it or you will put too much stress on the stitching at the zipper.
