I'm not selling mine - I'm trying to put the damn think back together, not take bits off it : )
If you got hold of one, I could do it - I've got the cutting die. Not sure how I'd go about getting the measurement, I'd need to think about that. I do have my original servo so could base it on that, but the clevis pin thin is screwed on to the new one (fitted).
Don't ask me exactly what Mk3 servo you need - I can't remember - but there is bound to be a post on here somewhere that addresses that problem. Have a search and then hit up ebay. You run the same risk as anyone else with a used servo - it might be buggered (I'm nowhere near being able to test mine!), and if it turns out to be, and you've had it modded, you won't be able to return it.
If you find one and you want me to have a go then let me know. I don't think I'd charge you - that could get a bit awkward if something goes wrong, but if you were happy, you could donate to a charity for me.

I've bought drills and taps from them before and they were good though. Proper name for the holder is a die stock.

What I can't remember is if the measurement from the servo mounting face (e.g. where the studs are) to the where the rod comes out is the same on the mk1 and mk3 servo.
Dimension A in the diagrams below. If the dimension is the same you can use the orange measurement (same as in my photo). If it is NOT the same then you need to use the green measurement (which is a bit trickier).
You need to take all the measurements as shown below:
From memory you'll cut the Mk3 rod just before the taper finishes. This actually makes it easier to get the thread cutting started.
As mentioned, if dimension A is the same on both servos then you measure like this.
One of the challenges is trying to hold the rod on the Mk3 servo whilst cutting the thread as there are no flats on it for a spanner. Guess you could file some flats. I ended up using some mole grips.
When you are cutting the thread, you need to make sure you keep the die square so the thread is even. Use a bit of oil and try not to cut too much in one go - you'll do a full turn on, then half turn back . Might be worth checking Youtube for thread cutting how-to.
Once you've cut the thread, fit the clevis thingy back on and get it set to the original measurement and you are good to go.
The servo I have only had 2 mounting bolts instead of 4 - didn't bother me, clearly it is good enough for the MK 3 Golf.
I'd do the modification before painting it (if you are going to).
Good luck!

What sort of accuracy is needed here? Is a ruler enough or is it more critical?

Ruler is fine - you can make fine adjustments (if required) on the main linkage but it shouldn't really be necessary.

At some point in the past somebody had spilled brake fluid on the servo so the paint was bubbling in some places.
I put a wire wheel in my drill and took all the old paint off the front and back and then gave it 6 coats of Hammerite.
With the hammerite dry I cut a 10x1.5 thread into the rod, and progress stopped at that point.
I ordered a new brake fluid reservoir to match my new 22mm servo which is still in the post, and the 14" wheels I need to fit to the car to cover the new discs are currently with the powdercoating company down the road.
Need to order discs and pads too, but overall we're seeing a good level of progress.
