I had mine apart many times, mine was off to the left and rubbed the playfield a bit. There is no adjustment in that direction. There is some play to tilt it and move it up and down, and messing with those back and forth you can get a little north and south adjustment out of it it that will help. I had pictures I took along the way, if I can find the, I'll post.

The only way I was able to get it moved back right, was to remove the entire assembly and open up the holes that mounted to the playfield itself in the direction I wanted. I used a dremel and just slotted each hole in the direction I wanted ~.050" or so. Mark it with a marker and slowly go at it until the mark is gone.

Sounds like a pain, but honestly after everything else I tried it was very quick and easy just to remove the whole thing and open up those holes. I spent so many hours trying other options, and maybe 20 minutes doing that.
