What about the adjustments on the yoke cover? I don't remember if they're just for centering. The "T" shaped magnet, on the side of the yoke should have an effect on the pincushioning.

Yeah, that has no effect. This is a rebuilt CRT and the neck is a little crooked which may be throwing things off.

A little. Mostly it effects the horizontal linearity.

OK, I didn't realize you could not only bent the "T" but also twist it.

It's still a little warped in the upper-right, but not too bad I think.

That looks pretty darn good to me. Seems to have improved the focus, too.
