Is there any saving list crank arm? The first couple of threads are stripped but you can see there’s good threads about 1/3 of the way down. I feel like if I could get my crank puller to thread straight, I could straighten these threads out, but I don’t wanna make it worse. Advice?

They look pretty bad. You could try and chase the threads, but will they even hold?
You can have it repaired with an insert, though that’ll probably need a professional unless you’re particularly skilled.
Depends how much the crank arms worth to you, but I’d probably replace.
In theory you can buy whats called a tap and use it to refinish the threads but in practice these probably won’t be cheap and unless you know what you are doing you could cause more damage. Why do you need to sort the threads out?
