M211 crankase ventiloation valve guts

[firefox]

Does anyone know where ai can get the guts to my crankase ventilation valve?
Opened up today and there is nothing inside, so I am missing a tapered valve, spring
and spring retainer?
Thanks for any leads or suggestions.

It is probably the same as any GMC PCV valve of that era. I can probably turn up an extra one but it'll be a week before I have a chance to check.
