Most bent crankshafts from a crash can be straightened, at least that is my experience.
I get a kick out of repairing things, rather than just replacing them, or buying new parts.

I learned how to true and straighten cranks from the Pro's back in the 70's....I'm very
good at it.....I've been doing it for 35 years, professionally. Send me your bent crank,
and I will straighten it for free.....no problem.
