The main cab arch bar frame on mine was twisted and it seems to been made that way, other cab 11 owners have also noticed the same problem when it comes to assembly.

Point well made Mike, the arch bar is a particular issue to fit correctly also the floor plates around the front wheel wells can be an issue (there are two different sizes depending on the date of manufacture). The 12 cabs seem to be a better fit all round but once again the arch bar can be an issue particularly on the front mountings. I have found the best way to assemble the cabs is to put as much as you can together loosely then carefully jack the cab floor and/ or frame to close the gaps and go round several times pulling up all the bolts until a reasonable fit is achieved. Chevrolet in particular have metal packing pieces inserted in things like wing and step brackets and shock absorber mounts to tilt or twist the brackets to fit these need to be in place or else they will not line up.
