Usable or junk??

so this is the original k frame out of a 72 demon and it looks like it was hit on something, hard.

I currently need a slant k frame and this guy is sitting on the pile, quickly available but i am wondering if the dent should be a deal breaker or not. There is no noticeable frame damage on the car it came out of.

Do you guys think it would be OK to try to straighten it and use it or do you think it will throw off vital geometry and should be canned?
