What to do about a bent frame???

[B_Bob]

Hey guys, sooooooo I got a little problemo......... I was poking around under my truck, getting ready to take it apart to swap crossmember, when I noticed that the frame rails forward of the crossmember are bent. I hate to put a bunch of work into a frame that is bent, so the question is, what do I do about it?
I could:

1. Not worry about it as it seems to only be forward of the crossmember.

2. Take it to a shop to have it straightened out. (how many $? will it be 100% straight?)

3. Get a new frame.

I just don't want to throw good money after bad. I have a line on a SWB 1965 rolling chassis for 1k. Seems a little steep, but would solve my problem.

So, what do you guys think?

OK, go...............
