MOOG Upper A arm offset bushings.

I bought the first pair of offset bushings from a member here. Those included nothing more. I recently purchased the second pair from O'Riellys Auto Parts. These include the instruction sheet which says both arrows point toward the ball joint. These also have 4 end caps or ferrules to be pressed in.
I assume the ferrules compensate for a difference in bolt diameters per various applications. More questions than answers for sure.
