ASP is 25% ud on accessory belt, and 10% ud on a/c belt.

does it look like this?

yea i guess it does . mine has a wider belt in the front or at least i guess the view you are showing me is the front and a smaller or thinner belt on the rear which is bigger than the front pulley if that makes sense

Yes, the front accesory belt is a 6 rib, the a/c belt is a 4 rib.

If you do have an ASP, the Gatorback belt #s you will need are:

Accessory: 4060775
A/C: 4040410

See my above post for correct belt sizes.
