Frame Repair -- NEED HELP!

[bddcustoms]

I have a 1969 LWB C20. Some time ago, before I purchased it, it apparently took a shot just in front of the driver's side front wheel. It's not so much damaged as it is "off". The body panels in that area (driver's side front fender and hood) have seam alignment problems. Even when I replaced the damaged fender, things still didn't line up right. As I've been working with the frame for some unrelated modifications, I'm looking to have the damage from that accident dealt with finally. Thought I'd start here since this is where I get all my other answers.

To the naked eye, the bare frame looks strait and square. In fact it is, except for the very front, from the cross member that sits below the radiator forward. As you can see in the pix, while the rest of the frame is level, in that area, the driver's side (impact side) is about an inch higher than the passenger side, and the frame rails are slightly off-square toward the passenger side (again, impact direction). I've never dealt with this type of repair before, and I don't assume I can (or can't for that matter) deal with it myself. But I like to be educated, even when I work with shops and specialists. So, fellas, what should I know or do about this type of problem?

Thanks.
