Front End Suspension Nightmare

Do you have metal working skills? From what I'm understanding you're going to have to bend where the strut rod is attached to the frame...either that or cut the piece off and weld in a new one. Those are the two options that spring to mind, I've never had that problem. If you do try to bend it back you're going to need heat but it will take alot and could change the properties of the steel to where it is much weaker than it originally was, unless you do heat treating to it. I don't know the feasibility of cutting it off and welding in either an entire new piece or cutting off the bent part and fab up a new mounting point for the strut rod and welding it in. I hope my post wasn't too muddled up, but do you have these kind of skills? If not you need to make friends with a welder. Hopefully there are some more guys on here with some different solutions for you. Goodluck!

EDIT: A picture of the damage would help too.

First, update your profile with your location so someone near you can offer to help-need to know where you are. If you are uncomfortable with that, no problem, you can limit the entry to the state you are in.
Next, we REALLY need to see some good pictures of the damage to determine if you can straighten it, or if you need to cut it out and replace it.
I just went through this problem on my 66 project. I whaled on it with a big hammer and a port-a-power. But I only needed to move the mount surface less than an inch. I took a bunch of measurements, pressed it out past what I needed, and it came back to where it should be. Alignment guy was happy. (I was ecstatic..to say the least). So, it may not be as bad as you describe, cause my alignment guy made it sound like the end of the world...
Try to get some pictures posted up. It will be easir with a photo hosting service like photobucket or some other hosting service. We can help with that too.
Oh, if it's a 70, you have more options cause it's moderatly adjustable. You can get away with replacig the mount, and the alignment guy can compensate for any "minor" placement errors of the new mount by adjusting the strut rod.

The strut mounts on my 69 Cougar were bent when I got the car. Every time I got the car aligned for a few years I was told about it, but they were able to adjust around the problem. Finally I had Marlon at Marlo's in Chatsworth fix it. He heated, bent and re-welded the brackets so they are like new. At the same time he installed new bushings and cleaned and painted the struts. The cost was fairly reasonable.

Your going to need to get someone with some metalworking skills (and tools) to help you with that one.
