The factory tach in my 67 rs/ss has not worked properly in a while. Replacements if you can find one are expensive. Are there any reputable repair shops for tachometers? Can a 33 year old tach be repaired?
I just had my tach rebuilt. I used a company out of California called "Palo Alto Speedo"
718 Emerson St. Palo Alto 94301-2410
I totally burned mine up with a bad wiring harness. A total rebuild of my original 69 tach was $100.00. Ususally it's around $35-$40 dollars depending on the problems. Work is good and comes with a warranty.
