No there was only the one run of this model. They ran from 1973 to 1974. I've done a VC-Mustang ID post which I have just updated last night. Which shows the different models and how to tell them apart. Your engine (if still the original) should start with 11173 or 11174 depending on year made...and thanks I would appreciate that photo as then I will be able to start the search knowing now what I'm looking for.
