GMC w/ Bent Frame

[KY_GMC]

During the dis-assembly of the truck, we noticed that the front frame horns were bent. Once I saw this, the pieces started making sense. The bumper was pushed to the right and the core support didn't fit like it should.

Here is the build thread: http://67-72chevytrucks.com/vboard/s...d.php?t=592157

Picture is post #6 shows the left horn bows to the left and the core support bracket is bent.

I have been talking to frame shops around here and they are hesitant to straighten the frame now that all of the sheet metal is off of it. They want to straighten the frame to match the sheet metal. Well, the sheet metal wasn't straight to begin with.

Anyway, has anyone had any experience straightening frames without the body on the truck?

One shop mentioned that the new frame racks are all computerized and that translating old shop manuals to computer measurements would take forever.

Looking for some input on how to proceed.
