Hmmm this looks suspicious

No offence taken :-D I believe all 1970 pink cars had the code "FM3" on the fender tag. Only a very, very small amount were built in 1971 that were pink, those cars had the "999" paint code. Here is a pic of the one in my garage, purchased from the original owner, "FM3" on the tag and build sheet as well.
