Locking RL-02 Heads

Quick question, how does one make sure the heads of a RL-02 drive are locked? I'm supposed to be picking one up this weekend (mainly for the Q-Bus controller and diskpacks). I want to make sure I transport it correctly since I might need it for my PDP-11/44 (still don't know the state of it's drives. On another note, anyone have any recommendations on where to get some RAM boards for a /44? Once I have the packs that will be the only thing I'll need (assuming everything works). Zane | Zane H.
