tachometer

Greetings all, So I decided to keep the 66 L-79 tach. I was wondering If anybody and I mean anybody would have a picture of the base alone??? I work in a CNC shop and would be able to make it but I need some kind of picture. Anykind will do. I will reverse engineer it. OR does anybody know any...

-------------------------------------------------------------------------------- Guys, I have one laying around. Yes it needs a rebuild and does not have the tach base and the Chevy emblem on the front (rubber) is missing and the screw in the back is missing as well. There is great debate on...

Anyone have an idea why the factory tach, would barley register? Increasing Engine RPM will move the needle but only so slightly, barely. New Tach, new wiring.

I cant seem to find a definitive answer to which tach was in the 71. Is it the round or the straight? all over google I see both. Please help wanting to put in and want it to be correct. Thank you!
