SB Pulley Help Please

Ok Joe, Im not trying to confuse things, but an AC would have 2 sheaves/grooves would it not?? Dont ALL non AC have one groove?? Here I go confusing the shite outta things!!

no, not on a 70-up car.


on a 70-up a/c car the twin belts go: crank,a/c compressor and the alt. the single belt goes: wp,power steering and crank.


check it out.. kinda hard to see but the twin belts go behind the wp pulley..
