Fitting OEM carbon diffuser - help/hints/tips/template

[Calps]

I was fortunate enough to find a carbon aero diffuser recently, and hoping to fit in the coming weeks.

I sized it up for fitment over the weekend, but, no matter how straightforward I think it is, I can't get shot of the idea that I may b@lls up the modification of the rear bumper.

Would anyone who has fitted this previously have any pointers, or even a template/guide that they could recommend?

(current approach will be to cut away, piece by piece, until it fits)
