I have lots of them in stock.  Just counted them up yesterday while doing inventory.  From my <www.frankcondelli.com/sales.htm> webpage :  O-ring, oil dipstick tube to engine, N 900 322 03 -  $2.80     It's a pretty standard O-ring although it may be special as they are green from VW which indicates to me they may be special for high heat use.
