Yeah I've just been less than impressed with the quality of anything from the parts stores. Ebay has a lot of NOS GM stuff like this but I just don't know the GM part number or nomenclature to search by.

Thanks! Looks like 3994239 is for the passenger side I showed in the photo. 3989350 is for the driver's side (the D shaped grommet that the pcv valve fits into). May I ask what resource you use to look up GM part numbers for our trucks?
