Looking for a pair of DEC RL02 drives, working or otherwise

Yes I think so too.

If you have the version of the RL02 that can be jumpered for either
RL01 or RL02 use, yes.  I've seen people put switches on a plate under
the lid (over the old brush area) so that you dismount an RL02K, flip
the switches, mount an RL01K, then read it.  One of the tricks is to
be sure to write-protect the RL01 pack in a modified RL02.

Yep.  I got an RL01 in 1985 to use with an RL8A and my PDP-8/a, then
it came in handy in 1987 when I got a gig where I needed my own PDP-11
to code at home and the RL01 was perfect for the boot volume (I
borrowed an RL02 from my boss for the customer data volume).  Plenty
of room for the OS and my code.

Fantastic drives both.
