64½ List of Differences

On a first view it should be easy to determine the build date if you start checking the VIN of a car, but in this case it's not so easy. Ford decided that the early mustang will get the "65" status from beginning and so every serial number started with 5Fxxxxxx instead of 4Fxxxxxx. <BR>This caused a 18th month production time for the 65 mustang! The official transition date from 64½ to 65 and also the latest scheduled build date is the 31st of July. The start of the second production run of a 65 mustang was the the 1st of August. Being a weekend date the first registered scheduled build date was the 4th of August. Before that date a total of 121538 early 64½ mustangs had been build.

Regardless what the official view of Ford about the model year of this cars is, there are reasons enough to differ. So if you are interested to determine surely if your mustang is a 64½ there are some rules which don't have exceptions:
- every VIN has to start with "5"
- there doesn't exist a 64½ fastback
- there doesn't exist a 64½ luxury or GT option
- every D,F,U engine coded early mustang is a 64½
- every 64½ must have an generator
- every 64½ must be build in Dearborn (march to august) or San Jose (13 th of July to august)

Use the 64½ Decode Info to check if the dataplate options (Date code, DSO, Paintcode,...) match the requirements for a 64½ production mustang. Also this should be enough to answer the first round of questions, but what's about the other, over 100 differences between these two production years? When I searched inside the worldwide web I found several pages listing the differences, but most of them were incomplete and mostly usable for helping to determine which car it is. I wanna to go a step further with showing every difference to build up enough information for concourse correct restoration and so I decided to build up my own list.
In a first step I set up my 64½ parts page (check inside the Gallery), where you can see some of the special 64 1/2 parts.
What you see here isn't the holy bible of mustang knowledge, but I tried to do my very best to built up a correct and complete list. I hope that there are a lot of early-mustang friends out there who will help me to get the errors out and to finish it some day ...

FORD MUSTANG OPTIONS
RELEASE PM'S, MONDAY, APRIL 13, 1964

The new Mustang from the Ford Division of Ford Motor Company combines the sporty, the stylish and the practical -- and offers them in any combination or degree.
In effect, through its many standard equipment features and a wide customer choice of options, the new Mustang is actually three cars in one.
Standard equipment features of all Mustangs include color-keyed, all vinyl interior and molded nylon carpeting; foam padded bucket seats; a floor mounted transmission shift lever; padded instrument panel; automatic glove box and courtesy lights; arm rests; cigarette lighter; full wheel covers; and many other standard items which are either unavailable or are extra-cost options on most other makes.
The basic Mustang is particularly suited to the smaller family or to the family looking for a second or third car. It features compact economy and low initial cost with all of the long-life, take-care features of other, more expensive cars. It combines driving fun with a sporty appearance and the practicality of a rear seat and adequate trunk space.
It also provides a highly versatile foundation on which the buyer can literally custom-tailor his own special kind of car.

The Mustang becomes a sports car for street or competition use through a selection of performance options. The performance-minded may select from three V-8 engines ranging up to 271 horsepower. He may add a 4-speed transmission, quick ratio steering, or a Rally-Pac with tachometer and clock. A special handling package -- priced at less than $40 -- includes heavy-duty coil front springs, heavy duty semi-elliptical rear leaf springs, special shock absorbers, an extra-large diameter stabilizer bar in the suspension geometry to provide flat cornering, 6.50 x 14 tires, and the fast-ratio steering gear. He can even order 15-inch wheels and sports tires, limited-slip differential, and a heavy-duty battery.
The Mustang becomes a luxury car with such options as a vinyl-covered hard top, a full-length console between the front bucket seats, a remote-control trunk release, a rear-seat radio speaker, an accent pin stripe around the body sculpturing, tinted glass and air conditioning. Other comfort and convenience options include power brakes and steering, an automatic transmission, and a power operated convertible top.
