1964 1/2 and 1965 Differences


1964 1/2 and 1965 Differences

Differences between the 1964 1/2 and 1965 Ford Mustangs

This is an overview to help  determine if your car is a 1964 1/2 or not.  The car may have all of the items listed, or just a few.  This can be due to variations in production lines and  parts supply  at that plant.  Some items can carry over into the 65 production line, as people on the line would use up what they had. There may be other detail items, such as casting numbers, that have been intentionally missed due to space.

    I guess you confirm what my fried had told me about the Mustang fastback did not come out until 1965. I had put in a order for a mustang comfortable but it did not come in in time and I had to have a car, there was a metal-flake gray fastback setting on the show room flour so I got it. It was the first one in Amarillo Texas and being a young kid just figured that since it was 1964 when I bought it ment that it was a 64 1/2 but I guess it was a 65.

    I am kin to some Dawson in fact my mother was a Dawson. Have a Blessed day

      Hi,
      Thanks for stopping by and leaving a comment.
      What a fantastic story about your Mustang. What happened to it or do you wish you still kept it? I just love stories like yours. A small world for us Dawsons.
      All the best.
      Mart.

        No I do not have it but yes I wished I did. Being a dumb kid I traded it for a 1968 Pontiac La mans because the paint started peeling on the mustang. About a week after I traded it I saw it on the car lot with a brand new paint job, I wanted it back then but just did not have the money to get it back.
