"they" seem to call it the 'rear suspension upper arm'. suzi has trailing arms and this center ball joint arrangement to locate the differential. i had only partially spaced it to reflect the suspension changes i made. i never had any problems with it(ran a couple of years without any spacer), but the ball joint was always at a funny angle. this spacer is 2", and seems to correct that. perhaps i'll never notice a difference.
sometimes i look for excuses to fondle suzi. i think i should fiddle with her rear drive shaft. i think it should be longer. i'm thinking of adding a 1/2" spacer to the diff. end. this is where it sticks into the transmission tail piece(static load).
that's a 1/4" gap, and it could stuff in there better than an inch, i've never had it drop out, why worry? just seems that it's supposed to be "in there" more. i never noticed what it was like stock.
