Need To Borrow A HeliCoil Tap

[CanadianGTR]

Hey guys,
Stripped out a caliper mount on one of my formula car uprights, and was wondering if anyone has a 3/8"-16 helicoil tap I can borrow for an afternoon.
Hell I can even bring the upright and helicoil to you and you can do it if you're not comfortable lending out a $40 tap.

Figured I would ask on here before being forced to buy the $77+tax kit just to tap one hole.

I can give the generous lender a $40 dollar deposit if need be.

Thanks in advance.

If you can show me where someone respectable has said that you don't need to use a heli-coil (STI) tap when tapping for a heli-coil... I'll do it.
Until then, everything I've ever known/been taught/seen professionals do tells me that I need a special tap.

I've heli-coiled hundreds of holes and have never, ever used a standard tap.

I'm not shitting on your advice here, just wondering why they make the proper oversized helicoil taps if you can just use a standard one... and why in any of my dealings with fabricators/race mechanics/car builders I've never been told about it.

Who knows, maybe it will work... I'm not saying it outright won't work...
However, I would then be using - I'm assuming - a 7/16-14 tap and inserting the helicoil (3/8-16) into the hole. This would stretch the heli-coil slightly, no? The hole you're inserting the helicoil into has to have to same thread pitch as the helicoil itself. So unless they make a 7/16-16 tap I'm not aware of, I don't think it would work out.

It MIGHT work if you just jam the bolt in there and call it a day... but this is my race car, and it's a caliper mount, and I really don't want to mess around with forcing a bolt with a 16 thread pitch into an insert that no has a 14 thread pitch just because I wanted to save a few bucks.

Again, I could be wrong.

Sorry for the long post.

EDIT:
On a side note, they used a special helicoil tap in the video, not a standard one from Canadian Tire.
