I didn't realize they measured to top or bottom of holes. Seems strange, but it works.
Ever other hole location I've ever seen was to center.
Thanks for pointing that out. I'm going to be setting up my cab for patch panel work soon and would have blindly used the center of the holes.
I was quite surprised too to be honest.
I have set up my frame to be level and am then using a laser level to ensure key points on the cab are where they are supposed to be (which as of now, they are not!). A prior poster had indicated that this would not work but I am pretty confused as to why not as the FAM clearly states vertical dimensions from a zero line (and the frame top) to each hole or point so for me the laser makes that vertical measurement easy. He seemed to say that getting those measurements correct is not going to help if gaps at the bottom were incorrect. i.e. get the gaps correct and not the measurements from the FAM? At least that was how I read it. Anyway, I will plod on and post updates here in the event it helps others.
Once I get the cab leveled out with the threaded rods I will post photos. New frame should be here in 2-3 days.
