I was looking at a 69 Chevelle and the front end had been hit. The guy said that it had went up a curve and hit a sign. I noticed that the frame was bent up about 1/2" on the passengers side just behind where the bumper bracket is attached.
My question is how hard is it to get it back to it's original position? I'm concerned about the final fit of all the front end components like the fenders,grille,bumper.headlight bezels,etc.

Your best bet is take it to a local body shop,and have them put it on the frame machine.I had one done for $200 and it took them a couple hours.Better to be safe then sorry latter when parts dont line up.
