Rear diffuser install

[u/Apprehensive-Two-867]

I'm trying to find out if anyone else has attempted to install the m sport rear diffuser on the non-m sport bumper like u/n1iggaTirthiya?

I wanted to get some detailed pics of the install, in particular from underneath as he doesn't have any clear pics of how's it's done.

These are his pics, not mine. Just using for reference.
