Does anyone know what size nut goes on the motor mount?

I was under my truck and one of the bottom side nuts are gone! The lug nut I tried didn’t fit so I’m guessing it’s M12x1.25 or M14, anyone know off hand?

Did you ever figure this out I’m rebuilding a motor and it did not come with the nuts for the mounts
