So I have a one owner car 1974 Manta, and I noticed that the VIN on the pillar differed from the Data plate on the frame rail by the first number of the actual serial number. I thought that it could be an easy enough mistake all these years, say the factory just got the number wrong. Well, then I looked today at some other tags, and they are the same way? , so I dug up info on a third from 1975, and the same thing...one number off.
So example VIN tag on the A pillar. OL77ND 9143333
obviously the data tag doesn't have the first letter designations, but model number start of 57814333
The number changed is off by one digit. I guess as long as you have a VIN plate and the body stamped number matches, you are good, but if you had to get inspected, and the data plate was the only thing to go by, you might have some problems. Can others verify this difference with other 50 series cars. Is this old news?
