It is funny that you guys call it a "windscreen".
For best results without damage, the rubber needs to be warm. I understand that it is cloudy and gloomy over there most of the time so you might need to use a heat gun or a halogen lamp. Softer rubber will flex more without damage.
Use plastic sticks with some type of lubricant like soapy water and pry a little at a time.

Thanks for your reply mr kern dog sure we call them windscreens, if I said windshield over here nobody would know what I was talking about.
And your very lucky living in CA,but we do now and again get good weather and use our mopars.
