You should look in the MTF Reference Library under the Attachment Interchange information for Large Frames. There are three tillers that could be fitted to the Large Frames: #18025, #18090, and # 18093. Any of these tillers can be fitted to any of the Large Frames, providing you are willing (and able) to change the lift arms as required, and have the right driveshaft length.
There were three different driveshafts as well: 47-1/4", 49-3/4", and 50-5/16". The notes section of the interchange information will tell you which arms and which driveshaft for each combination of tractor and tiller.
