Yes, there are codes. Look for two letters. The first letter will tell you the month and the second will tell you the year. Unfortunately, it is coded somewhat.
For example, the driver's window on our 67 shows GA, which is April 1966.
I would expect on your car, the second letter to be either an "A" for 1966 or a "Z" for 1967.
Post the letters once you find them.
Also, here is an interesting article.

There are date codes, but they won't mean the glass is original, just the correct (or not correct) dates. If you have not owned it long, then a previous owner/restorer could have installed correctly dated glass.
There is a two letter code. There is also a two letter and number code, like AS-1, AS2, that is not the date code. This is the American Standard specifications for the type of glass.
If you get the date codes for each piece, you can look them up in the NCRS 1953-1967 Corvette Specifications Guide or someone here can do that for you.
