Looking for lower unit parts for a 1986 Nissan NS55B. Need gear set, might be willing to purchase entire lower unit.

According to Tohatsu Guru (Elvin), the LU will interchange with:

50C
55B
60A
70A (The lower unit fits the 70 A, will work on the 70 A, but is not designed for the 70 A)

So, will all of the prop shaft related parts (gears, bearings, etc.) from a 70A work in the 55B lower unit, or will the complete lower unit from a 70A bolt onto the 55B?

Thanks for all the help!!!

Everything is the same except one bearing...Which will still fit in either one. The 55/50 bearing will eventually fly apart under the extra RPMs of the 60/70 one.
