Thanks for the comments!
No fitment issues but I'm using Betalink adhesive. It's pretty much like epoxy once it's on. I started by installing them from the wheel arch area and then pulling it towards the front so it was tight. Held it in place with painter's tape.
In all honesty, I had more trouble with the OEM deck spoiler (used Betalink on that eventually instead of 3M tape since that didn't work at all).
