Attaching Euro-mount to plaque

[Bhoesl]

Just shot my first elk a couple weeks ago and took the head to a beetle place for a European mount, should be done in a few months. In the mean-time I’m wanting to start making the wooden plaque to mount it on. How does everyone attach their euro mounts to the plaque?
Thanks

Toggle bolt inside the skull screwed through the back of the plaque. Totally hidden from view and rock solid. I do a second one to keep it from twisting on the plate with the weight of the antlers.

I also did a french cleat with an aluminum hanger from Lowes so the plaque sits flush to the wall.

This is a deer but I do 3/8”bolt through the bottom/back of the skull. I use a long needle nose fishing forces to reach in there and hold the head.

Thanks for the advice, I really like the toggle bolt idea. Only euro mount I’ve done before was a deer and I just ran a drywall screw through the back of the plaque and into the skull, but wanted something better for this elk.
