I restored a Sterling from this:

To this:

So feel free to PM any specific questions you have. I would be happy to try to help. I also owned a Sebring...for a couple of days. Bought it at a great price and re-sold it before I did any work. So I have some knowledge of that car as well.
To answer your windshield question....I'm not sure. Solid Sterling (www.solidsterling.com??) still had windshields available. They are custom, not from any specific production car. I would say with about 90% certainty that they will match. I would check with Solid Sterling to be sure. There is also a site....www.clubnova.com (I think?) which may help.
If you need any other help let me know.
