welcome to the site

I'd go one size bigger.
There are "coils" that insert in an oversize and hold a smaller bolt.

Drill and tap to a NPT size larger than the destroyed area. Screw in and Loctite a pipe plug. Use a steel plug with square extruded drive lug(solid plug) so you can cut it off even with the surface. Let the loctite cure over night, cut off the protruding plug, Drill and tap plug to the required size. You will have a steel insert in the aluminum that will never come out and never strip again.
Take care,Dave
