Trimmed bottom edge until it sat over the instrument panel. Trimmed the aft edge until the aft edge shows it is about 3/4" forward of plans. Tried various tools, but they all terrorfy me. The calmest is a dremel with a reinforced cutting wheel.
Kept trimming over the instrument panel until the profile between the turtleback and the canopy looks about right.
Marked a cutline about 1.6" above the longeron, dipping 1/2" down forward of the instrument panel. The frame foam is about 2.25" at the moment, the aim it to get them to meet, with the 1.5mm of skin and 3/16" of silicon gap as a fudge factor. Mark it three times, but it still looks like shit when I step back and look at it. Give up and drink some beer.
