Vikki, I have trim tag and VINs on three 1967 Firebirds with two known to be junked, 1 burned the other retired by another owner. Another item that may be of interest in your data collection that I noted was missing. On the 1967 cowl tag to the left of the build month/week codes is usually a three digit number. This gives even more detail to the sequencing of the car building. This number tells which car of the given week in sequence. A 100 with month/week codes 05B would be the 100th car build the second week of May, 1967. Might be better than the VIN since that number swings back and forth with V-8 versus OHC6 cars. The week sequence number will stay consistent regardless of engine installation. More trivia! Steve
