Dave....please show the tach in its current condition. That will help identify it. We've all made mistakes trying to 'clean-up' desirable parts.

I'am a subscriber to Mopar Action and hold Rick Ehrenberg in high regard in the Mopar camp. Similarly, there are users on this board that have excellent knowledge of GM products.

A before and after picture of your Tach will be most helpfull.
