Vin sequence question

[RichSchmidt]

I hear a lot of talk about mismatches between date codes and VIN sequences.I currently own 2 1973 F bordies and recently dismantled another.Here is what I have found.All are Norwood built cars,the first is my 73 camaro which was built in the first week of november 72,and the last 6 digits are 108,600.The second is my Firebird which was built in the last wek of november 72,and has VIN 103,123,and the last is the car I dismantled which is a firebird built in the 2nd week of november 72 and was vin 111,xxx.I dont remember the last 3.The camaro is an odd car out as far as the other numbers,but both the firebirds were identical 350 2 barrel espirts.I just find it interesting how different te 3 vin numbers are for such close date codes.
