992 SMOG Check Valves

[CamarosRus]

Anyone know if 992 Check Valves are easily found or scarce ????
What years of GM Smog used this Valve , This Part Number

Guess I need to run the complete # on EBAY

Chuck they are getting very difficult to find. I would use sources like pacecar jeff or Bill Hodel if I needed them.

For a NON numbers driver I always suggest:
Moroso 25900 Crankcase Evacuation System
to source valves for use as an option

Crane's Corvette sells these. They used to have used and replated.
