For most glass, the standard Triplex system should be fine, but I found what was apparently a 1970 glass on my 64 car. It had three dots above "Triplex". Had a look around and found the table below from a couple sources; like here;

From 70 and later, they dated the glass by month rather than quarter. Year is apparently the same, so it could be confusing when a later glass only had one dot above "Triplex". (I also found an "Industructo" with "BT" which could be either 1Q_62 or 1Q_66, Smart)
