Quick A arm question

[pritch]

I'm in the middle of this very thing right now. I was going to re-use all my old stuff, but I didn't like the way they were going on so I ordered new shafts and bushings.

A couple more questions-As the bushings thread into the arms, should the shoulder of the bushing/nut thread in all the way until it makes contact with the arm? Seems like I can get either the front or rear to touch, but not both.

And how-which way-do the seals go? They are different, top and bottom of course, but which is the inside face? Any pictures of properly installed seals?
