Hi Phillip! Last time I went to my local bearing distributor's counter in search of the NICE605, they ended up not finding a listing in their suppliers and cross-references, but I carried in the steering box and shaft, and we just measured it up for a common thrust bearing. Most bearing manufacturers have something that'll work, and it's not a hard-to-find size- pretty common, really.
Kevin- not a 'dumb' question, really- the 100's correct engine was the 10hp (K241). If the tractor's been well-used, it could be that Charlie's scenario is true- if they had an 8hp, and the 10hp died, they may have just slapped it in. Likewise, the decals, etc., as noted, or perhaps it's even got a different hood... mebbie it was a 70, someone put in an 8hp, and put on a 100 hood... (of course, that NEVER happens with Cubs)...
