This got me thinking, thanks. In my own 2619, the front shell bars near the "center" of the TM do most of the lifting for the Air Conditioner, but their adjusting screws are roughly 3/4 "loose", in exactly the way you described. AFAICT, my front shell sets are the same size (diameter). My 2619 might have been built with the wrong pair of front-most bars - a second set of "middle" bars, rather than a larger-diameter "front-most" pair.
