Ok, I know a bunch of you guys (and gals) are old VW folk from way back. Dig out your old stuff and look for a EMPI tach. It doesn't even have to work. It just needs to fill the hole and say EMPI on it.
I know there was more than one type. I'm not that picky. Just has to look good in the car at a glance. Heck, I may swap out the guts for something that actually works. (read: something OTHER than Nippon Electronics Corp stuff).
