european deer skull mount

[Lund1700Angler]

I have the skull cleaned and the plaque cut. My question is what is the best way to attach the skull to the plaque? I am thinking of using bondo in the skull cavity to put a couple of wood screws into. Can I get the bondo in a liquid form to fill the entire brain cavity?

Thanks,

i drilled holes in the wood plate and then wrapped wire around the skull and back through the plate and then twisted until it was tight. then i just ran a screw into the skull from there. i dont have any pics of the backside but here is the finished product.
