I have a good friend who has been searching for the manufacturer of these smaller instruments for his Deuce pickup without success. They are dual instruments with two functions in each. Don't know if the Speedometer is by the same manufacturer. Hoping someone here will have the answer for him. Thanks !
Ours go the other way, but maybe we could flip them around to point inward and add the cover like in the pic. Ours alr also 3-3/8, could probably mount them from the rear and make a smaller bezel. I believe those are AC gauges from an early GM Mark
