Mitsubishi M4851 5.25" (360K) disk alignment

I'm trying to align the heads on a Mitsubishi M4851-112U half height 5.25"
369K floppy disk drive.

I have an Accurite (Dysan) 224/2A analog alignment diskette. However, I
need to know:

What are the various test points for this drive?

How do I align the heads? The mechanism isn't something I've seen before
(not the usual movement of the stepper motor).

Anyone have any information? Herb Johnson has the manual, but it'll cost me
$40, so I'd like to see if someone can help me with just the relevant
details before I buy the whole manual.

Thanks, Matt
