I carry two spares in my center console for some odd reason. They date back to when I disemboweled the dash to replace the heater core. I just now walked out to the truck (it was still in the driveway!!) to check on the part number. The bag had disintegrated. And I am very sorry about that. They are available from the dealer, and I recall paying between $3 and $6 each for them, but it was worth it.
Try taking the remains to the dealer, who will probably have them in stock, or can get the number. You might be able to get them cheaper online from someone who sells AuVeCo parts. The AuVeCo catalog (paper and online) has a part number crossover. None of this cost-savings will be fast.
If it helps, I do have the AuVeCo number for the door panel clips.
