If you will take time out pull up a on-line parts list for each mower using the Craftsman model number and compare the part numbers of the tractors lift and control arms for each deck you will then have a general idea if they might fit.
I've done such and found this looking at parts lists is easier than just buying a deck that looks same then trying to make it fit onto another model tractor.
Close is no cigar when trying such.
I recently installed a 42 inch deck in place of a 46 inch deck on a cub cadet that was suppose to be a direct fit. No go. the lift arms had to be changed.
I've had to do about same when swapping craftsman decks and sometimes even the deck primary drive belt is different length.
