Marked and cut 3 big pieces off. One straight across the rear, about 4 inches wide. Most of the front tooling flange that more or less lays parallel to the canopy deck. Its like a pie wedge off of each front side. When I was done there was still about an inch of tooling to remove in the front and a bunch to cut off the back.
See how it now slopes along the canopy deck after a pie shaped piece was cut from each side.
4 inches off the rear
2 inches off the front middle, sweeping back as I approached the sides.
