His door sticker likely said 1969 since the 1970 model year started then. Some folks just do not realize it is still a '70.
Dave, my email to you bounced back for some reason, so I'll copy & paste my reply here........
Hi Dave,
Very cool, I do not get to see many broadcast sheets this early. Your Scheduled Production Date is 815 for August 15, 1969. (1970 model year)
The SPD is the date they hoped to built the car, not necessarily the day the car was actually built.
I see that this sheet is the one from inside the rear seat back, have you checked inside the backs of the front seat yet? If not, you may find one or two more sheets. If you find any for other cars, can you please let me know about them also?
I am trying to figure out why some cars were built way out of VIN sequence at times so sheets found in the wrong cars really help. :-)
Thanks!
