Joe. I'm lookin at the paperwork for the classic tach. manufactured by counterpart automotive but no contact info. I used it on a breaker type and then converted to accel system. both seem to read pretty good. I did have a issue. when I tightened the mounting nuts to the backing plate the little ground strap on the back of the tach kinda pushed in to the tach housing and caused a short in the circuit board. I had to place a washer on each stud to hold the backing plate off. a pop rivet washer was enough. The tach wouldn't read at all. drove me nuts. so it's sure not an old stewart-warner but seems to be workin good now.

Thanks....I did the washer trick to make sure the GND tab would make a clean contact also....I did wiggle the tach housing while running in the driveway and the tach droped off and almost didn't read again until I tapped on it.
I will post my phone call results asap
