The differences are the door, which doesn't really mater, the heads, the
linear positional, and reformat the pack. most regular packs can be
reformatted. There are 2 boards from the A which are interchangeable with
the F (most of the newer drives have them), and they have a few dip
switches that need to be changed.
Another neat option which i don't remember the part #, if the RK05 front
panel with the TU56 type rotary switches to change the drive ID # on the
fly. I think I kept a few for myself.

How could you quickly distinguish an RK05F spare head from a normal RK05
spare head?
I wasn't even aware that there were any differences. But I guess there
are, as you ask.
It's been close to 30 years since I touched an RK05F...
But the disk being fixed was the thing I knew. Is the optical thingy that
tells the head movement a part of the head?
