Need help with pulley questions

[bolinger06]

This is probably the dumbest question ever but i need to know what the very bottom pulley on my supercharger is. I have a v1 S-Trim. It's the lowest one, its plastic i'm pretty sure. It has it's own small bracket. I think i need to replace that and the idler pulley up top. It threw a belt today and the idler pulley is sitting sideways against the supercharger so i'm pretty sure the bearings are out of it. It was whining pretty bad right before it went out so it was on its way i guess. Thanks, Brady

Well i'm pretty sure i've figured out it's the tensioner pulley and the idler pulley. I'm just not sure where to order the idler pulley from? I read i could get the tensioner pulley from napa, but i'd rather just buy them together if it's possible from somewhere else?
