Has anyone here installed a windshield in their stang? Mine leaks from the upper corners and i am considering have it done professionally, although w/ anew gasket the bill will come out to 200 bucks, a little more than i expected. how difficult is it to due. keep in mind that mine has had a little chip in the lower center (i bought it like that) with half inch cracks radiating from it. they say at the glass shop they can probably avoid causing further damage, i question my own ability to do so.
