Lol, yeah. Doing collision work on late models with Car-O-Liner frame and measuring equipment that's accurate to +/- 1mm. On cars with no door or hood hinge adjustments, and no alignment adjustments other then toe where everything has to be spot on, and always chasing that zero on the measurements. Then go out there and work on mine and the right apron is welded on 3/16's longer then the left, the core support is welded on the frame rails 3/16 or so over to the left, the A pillars seem to be off 1/4 side to side. Good thing thing the square adjustment holes are big enough to move the door east to west coast. The under cab measurements are not square. Length is good but I think the right rear rail is in the car a touch toward centerline. The front mounts for the leafs are off side to side. I stopped measuring it was making me nuts. Still chasing the zero on the measurements lol I wouldn't have been a bodyman very long building stuff like that.
