Does anyone have a working SW 970 tach in their car? I've seen plenty of these tachs installed in Yenkos, but never saw one that actually functioned properly.
Not talking about solid state rewires or anything here either...a legit vintage tach and 990B box that really works? Are there really any out there?

In addition to an original working 970 tach with a 990B box in a '69 Yenko Camaro I sold earlier this year, I currently have an original 970 in my '67 Z/28 (which is equipped with K66 ignition) utilizing a 990A box. The tach works perfectly.
