Wanted:68 tach wire through firewall picture - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Adding a tach and looking for a pic of where the tach wire comes through the firewall. Also what size hole for the pass through grommet?
I could make a hole anywhere , but would like to stay close to factory.

Thank you, Joe
