front beam grease fittings

[MTT3107]

So, I got myself an adjustable front beam, and am in the process of transplanting everything from the old beam to the new one.
Still have to out and get the old ball joints pressed out, and get the new ones in.
Attached a few pics of the old joints.
Could be that they haven't been replaced since the car was assembled in Wolfsburg....


Tried to just screw in the old grease fittings, but noticed that the new beam has no threads in the holes for the fittings. So I need to get the proper tap to cut those threads.
Anybody here know the thread size of those fittings ?

Pretty sure it's 10Mx1 or maybe 8Mx1.25 Since you're tapping it yourself, I don't see how it really matters. Just use the correct fitting for whatever you tap it as.
