ask to look at it while still on the donor car before the pull it off. make sure u stick your head under to see if the car has ever bottomed out on the k-member, hit a curb on the k-member etc etc then give them the $$$ so they can pull it off.

 

You realize the work involved in changing this? Its just my opinion but First take it and see if it can be put back in alignment. If it can then the bend is mostly cosmedic. If it can't be take the alignment reading out to a body shop with a frame striaghtener. Get a quote to pull the frame back in postion. You can get a lot done in 3 hours on frame machine. I would still pick up a K-frame at some point and replace it when I had the motor out the next time. When you do the replacement it will be a great time to do some upgrades.

 

+1 to the frame machine.
