Not possible directly.
The 7958 disk drive only support the CS/80 command set.
The 41/71/75 only support the Filbert command set.

edit 1: added the reference section
edit 2: I have to check, but I would guess that CS/80 units should also support SS/80 since this protocol is a subset of the CS/80 protocol.
edit 3: added the amigo command set reference
