Sounds like she may have tweaked the cab from the wreck. Have taken measurements to see if the cab is still square and have good body mounts? I read some posts that the body mounts need to be in really good condition before doing this as they disintegrate during the years. I know you have it cut apart already, but I would start checking for square (like you said as good as the manufacturing allowed. You may find some issues along the pillars that are causing the issue too.
