Take your time tho, measure twice and cut once, mind you, it's not like you can uncut a bonnet, lol.
I also noticed that if I lined up the crosshair markings on the Aerocatch template and aim for 2 - 3mm below the centre of the strike stud, fitment is spot on.
But I guess it depends on how the curvature of your bonnet is since yours is different.
Good luck
