I know a few of you are going to disagree with me but I really don't think any sort of jig is necessary. The OP isn't doing any fabrication, purely replacing one riveted part for another. With 5-6 cross members it should square up as tightened. Again, these frames flex significantly and aren't perfect from the factory. If this was a hydro formed or unibody, I'd be more concerned.
The only way it would be out of spec is if there was some significant frame damage. Unfortunately as we were assembling the front suspension, we did find a bend in the right front rail, possibly from a previous collision. I brought the rolling chassis to a true frame shop that has been in business 50 years. All they do is frames, occasionally some suspension and alignment. He trammed the frame and straightened the rail and told me to bring it back when truck was done to double check it all. I believe it was about 4 hours to set up the tram and a hour to straighten. If it weren't for the bend, I wouldn't even have brought it over.
