Stripped the thread on my crank trying to get it off....

You can try a puller in it, arms tucked behind and threaded section on the BB axel. You may need to cut the chainring bolt arms off to get one in.
Or you can use a goood saw and cut it off/ bit of both technique.
It's not going to be possible to cut the same sized threads, a crank extractor would just pull them out in the future again.
I'd say the crank is toast. Do you actually have to remove it right now?
This is the last one I had to remove with the saw/ puller method.
The drive side is more of a pain obviously.
What cranks are they? I may have a spare kicking about.

I suspect that the thread was cut on the milling machine or lathe at Middleburn, not with a tap, so no need for a through-hole.
The only repair kit I've seen is this:
VAR, £120+ : https://www.vartools.com/en/repair-kit- ... r-p402.php
This cuts a bigger thread 24 x 1mm and has its own self-extracting bolts as replacement.
Designed to be possible to use with the crank still on the bike.
Might be able to find a bike shop that has one.
All the best,
