Tach from C60 to R10 ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is it possible to put the tach and gas gauge combo (or whole cluster w/ psi gauge) from a C60 truck into a 1987 chevy R10 pickup ? anyone ever done this before ? It is a 4.3 V6, would it work from a V8 or diesel ? any input would be greatly appreciated.

AMP gauge or VOLT gauge? MECHANICAL or ELETRICAL OIL gauge?
If it is AMP/MECHANICAL then not without a lot of work. As for the tach, you'd have to swap out the motor for the tach it's self (behind the faceplate) for one that's out of say an S-10 with the 4.3L or send the tach off to have it reworked to work with the 6 cylinder Unless of course the donor C60 had a 6 cylinder then I THINK IT MIGHT WORK BUT DON'T QUOTE ME ON THAT. jUST SPECULATION ON MY PART.
I did a similar swap 3 years ago but in my 90 burb with an electronic speedometer. Had a couple issues with the tach at the time but since I had a good working V8 factory tach I swapped out the face plates, played hell getting the needle reset right, but it's all still working just right.

Oh and you WILL have to repin your harness that plugs into the back of the cluster.

I think that it is a volt gauge, not exactly sure though as it doesnt say volts or amps. It is all electrical, I had it out and remember not having to play with anything except for the pin connector. Would the tach motor bolt right in from a S10 ?

I have a lead on one that I am going to pick up for $35 out of a C65, no clue what year it is, what years should I be looking for ?

I believe 77 or 78 is when they changed circuitry.
Before that they had the red epoxied components and they, AFAIK, are un-repairable.
