Aftermarket Tach in Stock Hole???
 

want to install a higher RPM tach in dash as i want to be able to get reading above 5K. i know a '70-'81 camaro tach will go right in, but was wanting to know if there was an aftermarket one that could be installed behind the lens WITHOUT CUTTING A HOLE in the lens, possibly with a shift light. anybody????? pics?????

It can be done, but you'll still have to cut a hole in the metal behinde the lens. Plus, now you'll be looking through 2 layers of scratched plastic.

HvyChvy,

Your picture puzzled me. Why is your gearshift indicator showing Park on the right side? What am I missing?

And it appears Rip was in gear when he took his picture. Don't let your foot off the brake!

What size of tachs are you guys using in there? What size fits best?

We have used both the Camaro and Sun Super II tachs. Any 3 3/4" tach will fit.

The Camaro tach fits nicely into the dash metal housing. Have to cut two holes, the front metal cover (round) and the rear metal cover (to match the Camaro tach). The trick is to get the tach centered in these two metal covers. The stock plactic, printed circuit can be used without any modifications. To wire the Camaro tach, (-) black wire to a ground (screw) location on the rear metal cover and printed circuit, (+) red wire to ign normally-on or to the fuse panel - unfused (use a 10amp inline fuse), green wire to coil or HEI - tach. The Camaro tach has no provision for a light.

The Sun tach requires, considerable more installation.
