You are not going to find a blower pulley with any grooves for the accessories. (water pump. alternator, PS pump, etc). This is where the tricky part comes in. If you want a three groovelower acc pulley you have to offset that extra distance with a longer blower snout. Meaning, if you have 3 grooves on the lower acc pulley then the blower snout will have to be longer than the snout for 1 or 2 groove lower acc pulley. Hope I didn't confuse you. You basically have to set the blower on the engine, hang the blower belt on the blower upper pulley and see how far it is from the harmonic balancer.
Kinda like this below.
