73-79 gauge cluster interchange

I have a 1974 F250 with the 100mph speedo and all gauges (no dummy lights). I recently found an immaculate cluster from a 1979 F350 with the same setup (except 80 mph speedo) in a junkyard, and was wondering if I could use it in my truck

The printed circuit boards are a different color, but everything else is same setup

If it won’t work, anybody got a good 1974 gauge cluster they want to trade?

Even if it won’t work, it was too nice to let it get crushed

I Would give it a try and measure the speed of both via GPS on the cellphone.

When it is internally geared in a different way the speed should be shown right, otherwise you will have to change the speedo gears in the gearbox.

Your 100 MPH cluster has the high beam light in a different place, & no fasten belts light.The added circuits required a different PC & plug.

I doubt the 85 MPH cluster would plug in to your harness.

The speedo would work fine with no changes.

I have a very nice 1973 cluster with gauges, but even that may be different than your 1974. We would have to compare the numbers on the back of the PC's & see if they are the same

Well, I had my really nice 100 MPH cluster listed on eBay, & it sold this morning. So, that option isn't available.

I do have lots of parts for these clusters, & have restored dozens of them. I may be able to put together something for you, or I may have the parts & advice to get your current cluster working for you. Let me know if I can help in any way.

The number one problem with these clusters is the backing that crumbles & falls apart. Followed by bad PC's. Gauges are usually good, speedos are pretty reliable. The cluster voltage regulators are usually good. Bulbs & bulb holders are often bad & need to be replaced or cleaned.
