My present windshield is broken so I bought another from a parted out car. I can get the old one out but how difficult is it to properly install the new one? I want to remove the old one and clean up and paint the gasket area first. I viewed a few Youtube videos and it looks a bit challenging. I'm debating if I should try it myself or pay someone else to do it. I have already bought a new gasket from Steele Rubber Products. Being as this is a project car I want to do all I can myself but I would hate to end up with a windshield leak.
