fire wall penetration
 

Hi I am getting ready to add a set of three gauges and a Steering column mounted tach to Our 63,, what makes a clean and proper access to the engine bay from inside the cab? this is what I am working with

The rubber plug above your air cleaner and on the right side(drivers side looking at it ) of the large firewall indentation in your picture works well. No need to drill another hole.
