You can either use a heli-coil kit for a 7/16-20 and use the original sized bolt OR you can step it up to 1/2-20 and use a BBC bolt. Either one should give you a serviceable bolt hole as long as you're careful and make sure you drill and tap the hole straight.

Either way, you're going to need to drill the original hole up to size for the correct tap, so the easiest and cheapest would be to use the 1/2-20 and the new bolt as 67_C30 posted.
