Are these single grove or double grove pullies?

 

For w-30 i would imagine they were 3 groove pulleys for the HD cooling option.

 

Independent of the W-30 option, three groves for a car with ac, alternator and power steering, two with just power steering and alternator, and one grove without any power (i.e. just an alternator). I'm looking for a single grove set-up. Thanks!

 

These are 2 groove pulleys
