    Tachometer replacement thoughts

    I did the full kit on my 87. My 87 is a TBI engine, Only issue I had was the tach needle was bouncing when I installed it. I replaced the ignition coil and the issue went away. The kit is expensive but worth it if you want the factory look. Im very happy with my install. It was pretty simple
