All B2000 and B2200 from 86 to 93 are interchangeable. That is, auto trans to auto trans... and standard trans to standard trans. Has to be like for like!
I have a used 5-speed fan blade from my '88 B2200, had some small cracks so I just bought a new one at the dealer a few years ago while I was replacing the radiator.
The requirements for the two setups are quite different. The Automatics work the engine and cooling system harder so they need more cooling capacity - hence the two row radiator vs one row for manuals. For even more cooling capability they increased the pitch of the fan and a different fan clutch.
