Welcome from Virginia. As I understand it. Actual build dates were not recorded.I need a little help from people more knowledgeable than me. I have a 69 Road Runner, the date code on the fender tag is 920. Would this be Sep 20, 1968 or 1969?
I would bet the production number on the tag would be pretty low for a 69 built in Sep 68.Welcome from Virginia. As I understand it. Actual build dates were not recorded.
The date on the tag is the SPD (scheduled production date) which is the date they hoped to build the car when the order was first entered into the system.
Actual builds varied & were not recorded anywhere on the cars. So 920 would be Sept 20th. However, Usually by September they were building the next model year. So I would expect your car was built Sep 1968.
