At the end of the original post there were three questions in quick succession. Here is my attempt to answer them, in order. I've taken the liberty to reword the questions.
1. Q: Does the Carlite term SUN-X equate to tinted glass, and vice-versa? A: Yes, SUN-X is the Ford term used for tinted glass. The term "tinted" might have had legal and/or marketing implications.
2. Q: Did all air conditioning equipped cars come with SUN-X (tinted) glass? A: That would only make sense, but I'm not positive of that.
3. Q: How were the clear glass windows identified? A: There were variations over time, but pretty much the same as SUN-X glass, but with the term "SUN-X" omitted.
Most of the Carlite glass included terms like "solid safety glass", "tempered", along with some industry and DOT specification references, and date code.
