Exjay1 -- just a follow-up question. You informed us that the new gasket is thicker than the older one (which I would expect since the new gasket hasn't been compressed by the AC unit). What about the other supports on the rear-end of the unit? (ie, see the "yummy" pic that shows the footprint of two square and one cross-member rubber supports; see also the second pic in post #6) Should those be replaced, too, due to the new, thicker gasket? or does the unit sit firmly on those rear rubber supports once the unit has been tightened to the mounting bracket? Thanks.
