The dash material is very soft. I started with my 2 1/2" air cutoff wheel cut the straight sections and then cut the corners with a utility knife. I had to enlarge the hole a little as instructions picture is not the best. When you install the cover over the meter make sure the window area of the new digital meter is centered in the hole before drilling for the push pins. The only other problem I had was with the screws that hold the dash on some were a little stubborn to remove.
