I don’t know which Expy you have but mine has the camera up front and I can’t figure out how you got to the back of the emblem. With the grille shutters and all I don’t know how you figured out where the nuts were in the first place. Did you take any pictures or have any pointers?
I have the paint drying on the rear one now but I gave up on the front one for the time being.
Mine has the camera too, it's a platinum, but I don't think that matters.
After i took the radiator cover thing off I managed to squeeze my hand in front of this radiator just to like my wrist.
At just the right angle with a light through the area where the hood latch is you can see the three studs for the 10mm nuts on the back of the emblem.
I used a small ratchet with about 8 inches of extensions to get to the nuts.
It wasn't too hard after I figured it out and my hands are pretty fat lol so I think most people should be able to do it.
