Heli-coil it. Honestly it's such a small bolt hole and it's in aluminum, you really don't even need to predrill before you tap it with the Heli-coil tap. Running the bolt through a die is not strictly necessary if you don't want to shell out the cash for a die. Just make sure the threads are nice and clean, no galled aluminum left on them. A box knife and some patience can cut out any aluminum in the threads.
