Greg - Can you tell us more about the tach installation. Are you using the Sun Tach face? - numbers and gradations. Nicely done!

Back in the '70's, I did a dash with a tach from a (Vega variant) Buick Skyhawk with a V-6 engine. It was the correct diameter and fit flush within the Corvair instrument bucket. Only needed to take a flat sheet of plastic stock (from my model making stock) and trace the clock filler plug and tach attachments and plug pin locations onto a single layout. I then wired it up to use the stock harnesses, as the tach only needs the signal wire added (the other two connections come off the existing Corvair harness).

It worked like a champ, looked pure GM, backlit correctly, etc. I sold it a couple of years ago, and the new owner has since traded the car off, so no chance of any pictures.

Mark,
Here is a photo of the instrument cluster of a 1978 Buick Skyhawk:

Yep, that's the one I used. I DID say that I did it back in that time period.

Am also using that same steering wheel and horn button on my project car, but in brown, to go with the saddle interior. I reworked a '66 Monza horn button center to take the place of the Buick emblem, but will have to cut down the ridge on the lock lever to make it work (the button is too shallow). Will look din-o-mite!

Thanks for the picture!

I posted a writeup on here a few years ago. I drew the design for it using AutoCAD. Unfortunately, I accidentally erased the file for it. I'm still mad about it as I put a lot of work getting it all lined up and matching to the factory gauges. I would have loved to sell the decals, or even ready to install tachs but it would be a lot of work to do it all over again. Interestingly, the numbers on the gauge face are not evenly spaced. I found this out when I printed an early version and overlayed on top of the Sun Pro.

I used a Sun Pro Tach and the mounting method that's on a Vair website somewhere. The face is actually a water-slide decal that's available from hobby shops. The sheets are blank and and can be fed into an ink or laserjet printer. My decal is mostly black with numbers. I removed the Sun Pro face and flipped it over. The back side of the face is brushed aluminum. The silver that shows on my gauge face is where the decal is clear and what you're seeing is the brushed aluminum. For the needle, I used one from a surplus gauge and trimmed the length.
