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.

    hi there. i have been trying to find out if there are any differences between the red interior colour `RED` for 1964 cars and 1965 cars? i have a 1964 260ci car with a red interior that has faded and needs replacing. i have contacted many suppliers in the USA but just cannot get a straight answer and was hoping you might be able to help me?
    all i have found out is that there is 1964/65 red,1965 red and brite red. does this mean 1964 and 1965 have the same shade of red interior and brite red is what says, a really brite red colour?
    thanks in advance.

    • Hi,
      I have been looking about and from what I can work out is that the 64 and 65 had the same colour. 66 had a different shade. Your door tag number should tell you and can be looked up on vin decoders. I wonder if anybody else reading this could confirm or correct me. I’m not a world authority unfortunately.
      I hope that helps a bit.
      Good question too.

    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

      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.

        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.
