Tracking a cars dates codes can be educational too. My T/A has a SPD of 417. The original engine has a final assembly date five days later, so my car was likey made at least 6 days late.
Do you happen to know if the AA1 Buffed Silver would hold up the cars build date due to the buffing. My AA1 Charger '68 had a SPD of Dec. 8, '67 and engine and tranny are Dec 21st and 13th, respectively (numbers matching units). I am curious if the optional paint had anything to do with the delay of 2 weeks.
