I did not drill a hole. I kept it as low profile as possible and snuck it between the dash pad and frame. Body color is TT1 avocado green and the interior is dark metallic green, no idea on code. The paint is Sherwin-Williams automotive. They only offered TT1 in there low-level paint. My painter would only use their top of the line, so I took their ultra 7000 color samples and matched it the best I could. It's extremely close.
