It looks like there is already a heli coil in the other hole. Someone probably used bolts that were too long and cracked it. A thread sert would be more than sufficient to repair that. Yeah, heli-coils are awesome but on something like that I would use a solid thread sert.
I cannot agree. There's no way in hades that cracked in two places bolt hole will hold a thread sert or a heli coil. Ain't happenin. At least not for long.
