AC delco PCV part # for a 06 Sierra?

Does anyone know the part number for a L59 Flex fuel 5.3 PCV valve in a 2006 Sierra?

I cant seem to find any PCV valve listed for a L59 5.3. I spotted the location of the PCV, It seems to be installed (I havent taken it out) So, some PCV valve has to take its spot.

If anyone knows the AC delco Part # please Let me know. Thank you.

I think the napa part# is a crb 29485. My truck isn't flex fuel, but there isn't much to the pcv valve on it. It doesn't have a spring or check ball or anything. I just used some carb cleaner to clean it out and put it back in.
