I used a double stick foam type tape piurchased from auto parts store, same kind used to attach emblems on a car etc.
Attached pieces to the delete plate ( trim it before attaching to fender )
Then just press it on over the antenna hole.

It's applied same as an emblem ( example the 5.0 emblem ) double stick tape is all.
You can see a layer of the tape between the fender and plate.
Make sure you get the dark gray or black double stick tape of course.
