58FLH stripped thread on swingarm frame lug?

I have a stripped out swingarm thread on the frame lug of a 58FLH so I'm trying to figure out what to do to fix it.
I've listed a few repair options below but would like your first hand experience before I go any further please?

I came across a pivot bolt that is 1" longer and I'm puzzled on its use as it would protrude past the frame lug and hit into the inner primary before it's even threaded all the way. Also, does this extra 1" bolt require a nut after it exits the frame lug? I'm obviously missing something here.

Another option I've seen is two over-sized self tapping pivot bolts (0.025" and 0.050").
Which one would be a better option and how successful is this option?

What about heli-coiling the frame lug or would welding an threaded insert be better?

A friend used a heli-coil to fix the same problem, it seemed to work. He sold the bike a year later, so I don't know if it lasted.

I used a heli-coil on my 59FL. It's been in for years with no problems.
