I strongly suggest that you use new glass especially for the windshield as old glass tends to have minute cracks and stone chips that will not be noticeable to you when looking at a digital photo from a responder to your request, but will be obvious when you head into the sun and cannot see s..t.
I have bought a 944, a 968 and a 914 windshield from

They are safe, reliable and fair.
