Hmmm, good question. I don't think I ever worried about this, but 
perhaps I should have. I think the L/R arms are the same length, 
but the top/bottoms aren't. IF it is really true that the two sides 
aren't really directly across from each other, then this must mean 
that the wheels are also staggered.

I'll have to take a good look at an axle beam to see if the lower 
bearings are staggered.

BTW, the most common mistake made when doing a type 3 
alignment is to ignore the instruction to leave the notch in the 
bottom ball joint pointing straight ahead.
