Are these Eccentric UCA Bushings?

Hate to be a Debbie Downer, but I would say you pressed them in opposite from what you want. I always install them like in the pic Vaanth posted. Front of the arm comes out and the rear goes in.

But wouldn’t that be case 1? I know I may be wrong but I just don’t see nor have I seen any explanation. Looking at the geometry I believe case 1 moves the front of the arm out as you describe. I can’t see how case 3 does anything but move the front in. What am i not seeing?
 
Maybe I should be more clear. Case 1 right passenger side. Case 3 left driver side.

Does that make sense?
 
It looks to me like all of the posted examples are correct, it's just confusing because they're all oriented differently...
 
Maybe this is a simpler take. With the bushing oriented this way in the picture below it will move the arm out. If this is correct than my installation is OK and is my orientation. Do you guys agree with this?

Crap I think I maybe wrong. I was thinking of the centerline as if a rod was going through the two holes. But there isn't. It should be thought of as a pin! In that cade I am backwards. I see it now and my mistake.

Case 1 is for the driver and case 3 is the passenger side. It’s a simple offset from a pin not axel.

All of the different perspectives are difficult to deal with. This is standing in front of the car looking towards the back of the car, seeing the arm head on...

The "rod" or center line is fixed. The arm moves about it.
 
It’s confusing because you have to use the correct frame of reference. The reference should be a fixed center line. The offset is strictly in the upper control arm so moving the control arm away from the centerline would require that the bushing be thinner at the inner point not thicker. Hence moving it outward!
 
Thanks everybody for helping me work through this. It was a bit confusing for me and took me a while for me to see the light.

This is really hurting my brain. Probably because I don’t know the alignment hardware yet as I haven’t done an alignment yet.

If the above diagram show is the front bushings. Front to back then this is how I have it. I used the same argument as you but EVERYONE has said this is incorrect.

I don’t know the history of this drawing above, but this indicates opposite, if you use the red arrows as the arrows pointed on the bushings. For example, on the passenger side front wheel, the right front pushing would be thicker on the outside not the inside as you indicated.
 
The simple explanation is that the arrow points the direction the arm moves. Arrow out, arm goes out. Arrow in, arm goes in. I guess you could throw it up or down too...
 
@nitro_rat Well one way to possibly explain the argument that it goes opposite to the diagram you put together (the way I also have it put on) is the following:

If the centerline is fixed. If you started with a standard non-offset bushing and pulled the front UCA toward you (out away from the car) the bushing would get thinner on the inside/car side and thicker outside toward the one pulling on it.

Right?

The best way to argue with my diagram is to leave it put together the opposite way and try to drive to the alignment shop with shopping cart wheels...

Installing the bushings as outlined in MOOG's directions gives you maximum positive camber. This orientation is both arrows OUT. Both arrows OUT pushes the entire arm OUT and tips out the top of the tire.
