Differences between First Generation Mustangs (64 1/2′ – 68′)

To an untrained eye, classic Ford Mustangs from the mid to late 1960s may not appear to have many differences distinguishing them from one another. Upon closer inspection, there are a few factors that make it easy to quickly identify the model year.

Ford Mustang History

The very fist production mustang was officially called a 1964 1/2, because it was produced halfway through the production year. You can tell a 1964 mustang from the 1965 mustang because of some small differences;

Differences between 64 1/2′ and 65′:

  1. The headlight extensions on a 1964 1/2 had a beveled edge, which was eliminated for the 1965 year.

  2. The lettering on the hood that says “mustang” was a little shorter, 4 3/8″ instead of 5″ on the 65’s.

The difference between a 65′ and a 66′ is a little easier to distinguish.

  1. The grille on a 65′ will have vertical bars, and the 66′ grille will not have them (except GTs).

  2. The side scoops on the 65′ have have a single scoop, while the 66′ has 3 horizontal trim pieces along the scoop.

  3. Stock hubcaps were also different for both years.

The 66′ and the 67′ is easier yet to tell apart.

  1. The body of the 67′ mustang is an inch and a half wider and two inched longer than the 66′. The hood, grille, bumpers, and taillights are all different on the 67′.

A 67′ and a 68′ have a lot in common, but you can tell the difference because of two very obvious difference. The 67′ has two plastic inserts in the side scoops, and the 68′ eliminated them both.

And, the 68′ mustang has rear and front fender reflectors that were a part of the body of the car.

These are the main differences between the early classic mustangs. Do you know of any other differences?
