72' Demon window removal

I wouldn't use a hair drier or any other heat tool that concentrates heat in one spot. Any flaw in the glass and it's going to crack. The back glass is pretty tough so you should be able to save the glass and gasket but the windshield will take a lot more care to keep fron breaking it. They should be readily available though so no biggie if you do. The gasket might be a different story. You might want to check and see if you can get one first before you start.
