Ok, I have this pretty bag of BYOAC tokens and these brand new mechs. The problem is these mechs are set up to take 1.075 tokens and the BYOAC are .984.
I've managed to explore them, but I'm missing what I need to do to make them work. Can someone far more knowledgeable about mechs give me guidance?
I have 3 pics. There is a hinged part on the mech that I can open up and get inside.
Help me BYOAC, you're my only hope.
I've tried to mark where the coin goes in and where I think it should go.

Open a little

Open a little wider

Thanks.
