[T42] replicator IBM 2878 and floppy drive

Maybe some info here would be useful:

Maybe FRU 84G8663?

Another option would be an UltraSlimBay floppy:

inside an enclosure:
Black IBM logo: FRU P/N 05K6187; ASM P/N 05K5907.
Blue IBM logo: FRU P/N 05K2643; ASM P/N 05K8805.

Do these two reference FRUs that you have set work on the IBM T42 connected to the replicator mini dock?
Because I see on the internet that i need the 05K8874 model.
