Idler Pully - I forgot how it goes on after changing my belts!

[Shaminii]

So I just changed my belts on my S13 SR20DET. In the process, I forgot how the idler pulley goes back on. I have a thick washer, thin washer, the pulley itself, metal plate, and a nut. I currently have it in this order: thick washer, pulley, thin washer, metal plate, nut. Can someone tell what order they go in. My car makes horrible jiggle, scrapping noises when the car is on and it sounds like its coming from the idler pulley. The car did not make those noises before changing my belts. The belts are tight or else it would make screechy noises.

Yes, I've checked and found another thread just like this but it was never answered. So I don't want to hear any whining from the low-life "search n00b" zilvia mobsters.

Please help me out ASAP.
