70 dart R/T???

Are you saying those cars would have both codes and the tips would be in the trunk or something? I have never seen a car with both codes. Of course, that doesn't mean there were none. Yes, there are cars with alpha numbers but no A Bodies with an "M". As far as I know the only cars with an "M" in the VON were AAR Cudas.

This is the first time I have seen this thread. Three things tipped me off right away. First, no A Body would have been an F series prototype, second, I don't think a car would ever have the code for duals without tips (N41) AND the code for chrome tips (N42), and third, the order number should be all numbers. There should not be an "M" in it. Not even a nice try.

If I remember correctly, about the only cars that had chrome tips as standard equipment were the 67 GTX and the T/A and AAR cars.

Why could an A Body not have been an F series prototype?

Numerous examples of N41 and N42 exist. Coding depends on year and applications.

M is a legitimate 70 VON letter and A bodies with an M VON code exist.

Numerous models came with Chome tips standard such as Super Bees and Coronet R/Ts

I've stayed out of this thread for a while but was was intriguing about the first post is the information supposedly on the tag. There is nothing that was posted that makes the tag info suspect or indicates by the data posted the car is not legitimate. The one thing that is interesting is it is supposedly a 383-4speed A/C car.

IF a car like this WAS built, all of the codes listed by the OP are codes you would expect or could find on the car described.
