The same way you remove any windshield. The tend to be a little brittle, and you can damage the perimeter with a wire. I have yet to successfully remove a front windshield. You can get extra long boxcutters at most auto paint dealers, and extra long blades for them as well. I saw the blades on ebay. The blades can also have saw teeth. You may have to remove the dash to get to the bottom of the windshield from inside. If you can add some heat to the urethane, it will be easier to cut.
