47-59 Speedo and Tach question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**TX3100Guy** · 10-18-2022, 05:09 PM

My 1953 truck has a 1959 261 cu/in engine and a four speed GM transmission. The transmission has the traditional speedo gear and cable setup to a mechanical speedo. The tach is driven by a mechanical tach generator mounted on the shaft of a magneto, not a distributor, with a cable from the tach generator to the dash tach.

I'm thinking that I'd like to convert the cable driven tach and speedo to a more electric version (not digital) and have been searching for some kind of sensors that would replace the cables from the tranny and the magneto tach generator and that would pair with a new set of dash gauges (speedo and tach)

Is anyone aware of a product(s) that would allow me make this transition?
