This seems to be a thread I would want to know more about too.. I have a -65 912 tach that I would want to make work with the -69 911 boxersix equiped VW...
Yes, I know that a 911 tach would be one option but the thing is that the faces on those have white digits dont they? I want the green digits on the 912 tach..
Is there any way to make the 912 tach into a 911 tach just by replacing some component in the tach??
