Does anyone know of a vendor that has stock of eight OEM 10mm Valve Adjustment Screws (022-109-451)? Reading about the poor quality reproductions being sold, I first checked with the local Porsche dealer who told me that none are in stock anywhere in the US. Online vendors for the OEM part number I checked list them as NLA.
Assuming the OEM parts are NLA, I read mixed reviews on the Kolb (Kolbenschmidt) brand reproductions - and since I plan to switch over to swivel-feet adjusters later this year anyway, I thought I would give the Kolb parts a try (my adjusters are in bad shape). FCP Euro stated they were in stock, but after placing the order I received an email stating that their supplier only has one in stock - so I canceled that order. Other vendors must use the same supplier because when I checked inventory of the Kolb part elsewhere they also stated only one available. I just noticed that AA lists the Kolb part. If I don't get any leads on OEM parts from folks here, I'll try calling AA tomorrow to see if they actually have eight of the Kolb parts on-hand. Thanks for any leads, Frank [Edit] I forgot to mention that I'm going to call a VW dealer tomorrow to see if they possibly have stock |

You could take the one you found and add it to the 7 here:

This is what I am running. I have a set of rocker arms done by Tabari ready to go that I will be selling. These are 10 mm. Click to open.

I prefer Thorstens adjusters due to the allen adjustment vs the flat (slot)
They are also made of tool steel |
