Corvette Cradle Shortining for width

[z06chevelle]

I have purchased a wrecked Corvette Z06 and am in the process of doing a build on a 67 cehvelle convertable like Poplar Hot Rodding's project 57 where they used the Corvette suspension and grafted it to the Chevelle frame. I am doing the same type of build, but with a twist. I am building my own frame for it and adding air ride suspension. I am trying to figure out the best way to cut the front cradle that came out of the Corvette so I can take a couple of inches out of it to make it a bit narower so the wheels will fit under the chevelle and not stick out. All the suspension and steering and engine mount to the cradle. I saw the article that was posted on this build, but they did not go in to any detail on how they did the cutting and rewelding of the cradle. Anyone done this or have any ideas? Any help would be appreciated.

Thanks, Jim.
