So I bought an aftermarket tachometer. While deciding where I would mount it i noticed that between the two heater vents is a circle indented in the dash board. What was supposed to go there? A clock maybe? Anyone know how difficult it might be to drill that out with a dremel and run my wiring through the firewall and mount my tach there. Is there anything behind there that might make this tough? Planning to tackle this tomorrow. If I mount the tach somewhat turned in there I should be able to see it pretty well.
Any thoughts or advice would be appreciated. Thank you.
