Next thing is to tap them out with a 440 tap. Just don't go too far in cause the holes aren't very deep. Once the tap bottoms unscrew it then put some 440x3/8" screws in. If those ever come loose put a little CA in there like option one. Don't glue the screws in though cause when you take the screws out the plastic threads will come out with the screw.
