I have been all around my 1965 Barracuda trying to determine if it's an original Formula S car, having the original fender tag would certainly help. Your car has the correct valve covers for a Commando engine, but the "30" on the build sheet does tell me it's a 273-2bbl. car. The painted stripes could be ordered seperately, but only on a Barracuda model. I was told that all the V-8 cars in 1965 had a "V" as the first digit of the VIN, but mine has a "1" which supposedly means a slant-six car. My car has the 4-bbl., the correct engine dress package, and the high-compression pistons, but no tach nor is one mentioned on the copy of the original invoice I got from Chrysler. It does have the correct rear-valance which is set up for the resonator exhaust. So who knows what Ma Mopar put on the early 1965 Formula S cars? All we know is what they were supposed to have. If I can help you out with anything else please let me know.
