idler pulleys?

[horse_trader]

My 2002 6.6 dmax idler/bearing pulley failed (broken serpentine belt) and locating a replacement is harder than I guessed it would be...I've ordered through PM/Chevy dealer 2 for (imbarassed to mention) but you would think it would be off the shelf available.
Theses are the 2 flat rollers/bearings under the
altenator....
Any suggestions?
I'm looking to order a couple of spare bearings rollers (idlers?) and belt to have on hand.

Thanks for any assistance.

A little over a year ago, I needed to order an idler pulley to get the Project running. In this case, I needed to order one through the local GMC dealer - it wasn't an off-the-shelf item.
