Kubota Deck Numbers/Letters

[TC48DA Owner]

I have a kubota F2560 with a RCK60-F30 deck. Looking to upsize to a 72" deck and was told all of the 72" decks are the same and only the brackets - mounts are different. Additionally I was told to find a RC72 deck and the mounts from my current deck would bolt right up and the numbers after the dash designated the brackets and such. Anyone with any ideas on this one as I have located a 72" deck that is a possibility.
