2014 mustang gt Paxton spacer/pulley

[Go551]

Hello all,
My belt keeps skipping over 1 rib towards motor. My question is there a spacer that goes behind blower pulley that pushes pulley out 1/16”?

I've never seen a spacer between the blower and pulley. Check the ribbed idlers around the blower. I'd guess one of them needs to be spaced out.
