I bought my AAR from the original owner back in 1982. It has a SPD of 403 on the fender tag. The engine in it is a non T/A, no VIN or assembly stampings warranty block. The casting date on the block is 7-2-1970.
I was told by the original owner that he bought the car new in Oct. 1970. He also told me that the car already had something like 700 miles on it when he took delivery. It appears that the not T/A warranty block was installed before it was originally sold new.
The auto trans does have the correct VIN on it.
