I looked in the photo archive and Gene's site and couldn't find a clear answer for this. According to some notes I have from the Amana convention:
"When using offset upper A-arm bushings that if the bushing is in the front the arrow should point towards the ball joint. If installed in the rear the arrow should point away from the ball joint."
Therefore I would presume that if you are using two offset bushings in the upper arm they would both be installed as noted above. Front towards ball joint, rear away from the ball joint.
Is this correct?

Steve,
The arrows were not for us to use for caster.
Best to use logic and remember that you want the upper ball joint to
position toward the ear of the coach. on each side.
We have found that the geometry of the upper arm does not work well if
we install an off set on front and back,just do it in the back only.

Steve,
I've edited what you've noted below IN CAPS; hopefully it will clarify the
situation not confuse it!

I looked in the photo archive and Gene's site and couldn't find a clear
answer for this. According to some notes I have from the Amana convention:
"When using offset upper A-arm bushings that if the bushing is in the front
the arrow should point towards the ball joint WHICH WOULD LOCATE THE STEEL
SLEEVE AS FAR AWAY FROM THE BALL JOINT AS POSSIBLE. If installed in the rear
the arrow should point away from the ball joint WHICH WOULD LOCATE THE STEEL
SLEEVE AS CLOSE TO THE BALL JOINT AS POSSIBLE."
Therefore I would presume that if you are using two offset bushings in the
upper arm they would both be installed as noted above. Front towards ball
joint, rear away from the ball joint.
Is this correct?

Steve, I put offsets in the front and back. That is a mistake. The offsets in the front do no good what so ever. You just have a lot of adjustment that you cannot use. If you try your camber will be way off. Only put offset bushings in the rear as Jim K said earlier.

I should also have added that a single offset in the rear arm works
best. There are no additional benefits from using an offset in the
front ear of the control arms.
