I'm pretty sure they are the same. Is the part number different?

Sure it will fit if someone knows what they are doing. Functional and Legal, that is another story. There are part number considerations for sure. Need specifics, what is the plane and what is the windshield?

Is it legal to use a used windshield? I was under the impression that it was a bit of a gray area.

I’m not sure it’s a gray area, we’ve been doing it for 30 years. Is it wise? Depends.  Recently tried one from a wrecked plane and it broke on first pressure cycle in the hangar.  Expensive lesson. And there’s a couple guys selling windshields that have known history and/or fraudulent history.  Otherwise we have had good luck but it’s not something that I would recommend for someone in the field who does not have experience fitting these windshields that’s for sure.
