I have a 97 ssei. I'm wondering if anyone could tell me the sizes of the 3 idler pulleys that the supercharger belt runs on. I'm trying to order them on rockauto from work. Or if anyone could post a direct link to them for me. Please and thanks for any help.

Weird that they have multiple sizes. You can't measure yours?

They're still in the car and I'm at work for 12 hours unfortunately. I was just trying to get a jump on ordering them since I had to special order the belt from intense-racing. My brother in law looked at them and said they were different sizes and ones plastic?

Not sure on your year, but when I replaced the original idler on my 93 SE it was plastic and it didn't last long and has been replaced once already. You can usually find replacement bearings for your original idlers and have them replaced by a machine shop. I'd try and keep the metal idlers if you can.
