The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - 55.2-59 Factory tachometers???

**chev-obsession** · 09-09-2022, 12:58 PM

So I bought a box full of old tachometers. One of the tachs has 1957 GMC in sharpie. I’m trying to find out any info on these tachs and not having a lot of luck so I figured I would ask here. The longer body is throwing me off and also note the 3 prong electrical plug

Did the 55-59 trucks come with factory tachs? If so are these the correct factory tachometers? (Aside from the Stewart Warner)

Can anyone give me any kind of info on these?
