What's the best way to fix aluminum intake threaded hole for temp gauge sending unit?

LD 340 intakes are not cheap if you can find one. Saw 5 at Carlisle and all sellers had 5 as the first number in the price.
I know that. I'm tryin to get you to see loafin around on an internet forum ain't gettin your intake fixed. I'd have that beeotch fixed and onto the next project days ago. Chop chop Hopsing.
