Stripped holes in the case

Hi all!
In you efforts to do some while I am in there projects I have come across a stripped hole in the case used for installing the intermediate shaft cover. Would it be more wise to drill the hole a bit wider and re-tap the alloy or would a heli-coil be the better bet? As you can see by the image there is not a lot of material around the hole to begin with.

Unfortunately there is no material to tap.

Maybe tap it to the next larger size, just run the next size tap in and cut some new threads, I would prefer that to helicoils which you can still do if tapping fails.

A helicoil would be the much better option for me (they are easy to use, work well, and you retain the original bolt size) . . .

Timeserts all the way, don't waste your time with a helicoil. Been there done that, have the T-Shirt, CD and post card.

Helicoil is just fine when done right. That is a low torque boss, non-critical.

Conclusion

Thanks for all your input. I opted to up the bolt size and bore and tap to match. In the spirit of not having to revisit the stripped scenario I opted for a fastener that will be tough to apply enough torque to cause stripping again. Let me know your thoughts.

I don't mean to offend you but that looks like a bodged repair job.
Our cars have value and as such, they should always be repaired to the highest standard, IMO.
Time Certs would have essentially restored the threads and allowed you to use factory fasteners.

If you're into a real low torque on those it would be better to use allen head bolts and drill a hole through the head sideways and then safety wire them so they can't come loose and fall out.
