Where's the Mast Plug?

I'm wanting to do some maintenance on my H21 SE mast. I know it leaks because when I step it, water runs out the bottom near the rotator.

I seem to remember (way back when I was putting a comp tip on my H18) that there are some kind of plugs inside these mast. It seems like there was one way up just below the comptip and another one down low close to the base. I'd like to but a drain hole in just above the lower plug. does anybody know where the top of the plug would be?

Drawing says they are at the rotater bolt and just above. Looks like two.
