Venturi Stop Screw Part Number

[Pawel66]

Could you help with looking up the Mercedes part number for venturi stop screw?

Mine is broken. Yes, I could make a new one, but prefer nicely looking cut slot... All generic ones I can find and buy are for allen keys, do not have a straight cut slot for flat screwdriver.

I do not see this screw in the EPC. It is there on older drawings next to throttle, so it must have a part number. I found a lot of part numbers for linkage parts on the forum, but not for this screw...

It is part 65 on the picture, I think. I also wonder what is part 67?
