Hilux front leaves

[3VILC]

Random question, I've noticed the front leaf packs in the hilux seem to have 2 different designs both apparently factory. Some have all the leaves centered relative to the axle posistion, others (like mine) have all the lower leaves aligned towards the shackle end of the spring, ie. all but the bottom leaf goes right upto the shackle.
What is the difference between them or purpose of this?

Cheers,

Bump..Surely someone knows the difference
Unless the heavier ones are the diesel model ones i know they are supposed to be different, in which case they are wrong for my truck. Looking at luxs today i noticed 3 different arrangements in the front. Like mine all 6 leaves right to the back of the pack; a similar arrangement but back ends more spread out; and a much lighter looking pack that looks the same at the back as the front, 2 leaves right along and a few very short leaves in the middle at the bottom.
Could be just differing aftermarket designs tho i suppose. But im sure the 1st and last are both factory
