Full V8 Serpentine Belt Parts Listing Help

[07V8]

I'm diagnosing a slight startup squeal on my 078 V8 that goes away after about 60 seconds. Per the diagram below, there is one tensionar assmebly (with pulley), and two individual idler pulleys. I have been unable to locate individual part numbers for the auxiliary pulleys. Any help would be appreciated....below is that I have so far.

Tensioner Assembly: 16620-0W101

Tensioner Pulley (note this pulley is ALREADY installed on the above Tensioner): 16603-0W030

Idler 1 on diagram: ???

Idler 2 on diagram: 16604-50030

[MENTION=126194]07V8[/MENTION] I'm dealing with the same issue except my squeak is more persistent, about to change the belt (hence how I found this thread). What ended up being the issue to solve your squeak?

Here's the bando part you are looking for. Can't believe it's only $17 on Amazon. That is a steal to fix my squeal.
