Ignoring the one person trying to help you undo the damage. Brilliant!
I see you have an engine swap topic here and it looks like it was the cmc builder that butchered the mounts. If the center bolt is clamping the chassis and the engine mount brkt, you basically have no mount. There is no isolation. Only rubber should connect one side of the mount to the other.
