    Has anyone ever put an older Cluster in a 77. The 77 reads 100 MPH. Was wanting to put a 73 model in that is available that reads 120 MPH. I was wondering if the wiring is the same & if the Speedometer would read correctly etc.. My son's 77 needs a new cluster & we can't locate a 77 cluster.
    Thanks, Mike:)

    I don't know your answer, but if you do a search, I saw that topic being discussed in length. Was in the last week or two.

    I like the looks of the earlier one myself.
    I think 75 was the last year for it.
    Good luck

    The speedometers are interchangeable.

    There is a difference with the early and late model printed curcuit sheet that mounts on the back of the cluster. I think there is an extra curcuit added for late model economy idiot light. If idiot lights dont matter, then everything should interchange. When changing from 100 MPH to 120 MPH, don't forget to get your speedo calibrated.

    Where do you go to get them calibrated?
    Thanks, Mike:)

    Dennis,
    You don't need to calibrate (change the plastic trans. gear)when you change the speedo from 100 MPH to 120 MPH????????

    Don't know the exact years, but a cluster from a '71 Maverick would not plug into my '74 Maverick's wireing harness. The '74 plug was smaller then the 72's plug. You will probably have to take the clusters apart and and put the early guages in your '77 cluster. As far as the idiot lights, I "think" you should be able to swap the plastic film that clips into the back. Hard to explain without showing what I'm talking about...

    As far as I've seen, '74 was the last year of the 120 mph speedometers.

    Nope. The difference is in the speedometer its self. They just have stiffer springs in the 120 movement. Its easy enough to verify. Just take a drill and hook it up to each one and run the drill full speed. It will read the same mph on both.
