9/16 ×12 helicoil kit needed

[4554x4]

Well, stripped out the bolt holes on the front Dana 60 where the spring perch bolt to.
Do any of you happen to have a helicoil kit in this size that I might borrow?
Obviously I would need to pay you for the helicoils I used. I will also need a 37/64 drill bit.
I am not opposed to buying these items, but I likley will never have the need a second time!

I don't have one, but I'm wondering if you can just tap them 5/8" instead?

I have done this in the past on them and it worked, there isnt alot of meat left on the one side of the hole but it worked.

I have the tap and die but it's been years since I've used it and I can't find it anywhere. I got mine along with the helicoils from Fastenal
