Well that's kick ass!
How are the stock emblems attached?
The rear is held on with 3M foam tape. Apply liberal amounts of goo gone or wd40 around the emblem and let soak for 30 min. Park in sunlight or use a hair dryer to heat up emblem. Tape off around the area and then use a small flathead screwdriver or plastic putty knife and start prying up. It should release as you go around. Then just remove the tape still on the door, clean the area and apply the new badge.
On the front you need to remove the plastic radiator cover on top under the hood so you can access behind the emblem. The key here is you will remove the entire chrome bezel that holds the emblem. You can’t just remove the emblem.
When you reach behind on top you will feel two plastic tabs sticking out at a 45* angle. You should feel a little catch on top. Push it down until you hear it click. It should now feel smooth when you run a finger across it. There is a third tab on the bottom. You need to reach under the emblem through the grill to find it. Once all 3 are popped the bezel will come off.
Now you will see two nuts on the back. Remove them. The posts the nuts were on have a notch in them that holds the emblem in place. It is impossible to over come this notch. So grab a pair of pliers and twist the post. It will snap off at the notch and the emblem will pop off.
Then clean the face and apply the new emblem.
I did a bunch of prying with screw drivers and removing other nuts behind the emblem before I figured this out. This caused a few little nicks in the chrome bezel but nothing I can do about it.
