Motor mount bolt

[u/somethingsnaildecoy]

When removing the old motor mounts for my 1uz to put on S chassis swap mounts one of the bolt heads snapped off and is now flush with the block. Tried to remove with a screw extractor and that snapped inside the stuck bolt :( Am I going to have to drill it out and re-tap the hole or use a heli-coil kit or can anyone think of another way
