Pulley Difference?

[zZsKyZz]

I have a set of March Underdrive pullies [part number 1000] sitting here next to me at the shop and they are for a fox body [87-93]. I just went outside and sized them up on my car and they look to be exactly the same. Why do our cars [94+95] have a different part number and cost more? They seem like they would bolt right on with no problems... Plus, I can get em for $50 instead of $100..

Is this just a gimmik or is there a real reason?

Anyone?!

I thought it was something to do with the alignment/depth of the pullies being slightly different
But I can't confirm this. Hopefully someone has a better answer for ya

Or wait, isn't the WP puller different on foxes because of the clutch fan setup?
