Converstion Kit for Belly Mower

[TigerfaninAR]

/Pine posted a table where a RCK60-24B belly mower will fit a B7300 with a converstion kit. These readily available at the dealer? How much and how much effort will be required for the job of the kit and attaching mower?
Thanks and sorry for all the questions in the past two days. Tractor here tomorrow and just a little anxious.
