Ok, I just got off the phone with Joe Doyle, the man in charge of Registrations et al. He said that as long as the Mustang is modded, it is welcome on Saturday and that goes for any year Mustang. Sunday is limited to antiques.
His suggestion was to preregister (info on the link that I provided) and that way, he will approve the Registration. Joe handles all the preregistrations. My name is Rich and you can mention that I posted this information. That avoids someone at the gate not knowing what is a modification or not and speeds things up greatly. I think that you need to be at the gate by 12 noon on Saturday. There still is time to preregister.
