    I did also see Audi MK1 TT tail propshafts for sale on eBay. Mainly in the UK but through eBay global shipping they were actually pretty cheap. eg. 50 quid for the shaft, 38gbp for shipping. That's about $150ish AU.
    I can kind of understand what you are saying, but looking at the image I've posted of my current coupling and how it actually mounts and the slight difference in the newer part number item, I cant see an issue with it potentially working hey...

    Just un boxed this and measured.
    It all check out the same for the bolt hole centres and
    the O/D is actually a tad smaller than the gen 1 haldex / Mk4 type

    All in and running lads!!!

    Firstly, the tailshaft-haldex coupling…it lined up perfect to the tailshaft, BUT….I did have to drill out the three coupling-haldex flange bolt holes, because the quality of China parts just aren’t made to a very high standard of quality and the centres were 0.5mm off and one bolt wouldn’t line up perfectly with the haldex thread. Re drilled the three holes from 10.5mm to 11mm and it went on perfectly.

    I also successfully installed a JXB performance centre bearing carrier and confirmed with the owner/operator of JXB (for the first time, no one has tried this yet) that his kit for mk4 R32 (golf) works on a bora 2.8 4motion…and so he will be updating his website and products across the board to now accommodate this chassis in his lineup.

    Also, while I was under the car all day, I dropped the rear subframe and also installed a Darkside Developments 50/50 haldex bung and serviced the haldex.

    It drives quite differently now and the difference was immediately apparent when hard launching.
    I will upload photos later today ✌

    that's great news across the board mate.

    So do you think the flange bolts holes at 10.5mm were to mirror OE spec? Or do you think it was just sh*t chinese quality manufacturing?

    Also good news on the JXB stuff, although I assumed they would be the same as they share the same part numbers.

    Always been curious on the Darkside bung. Great (by great I mean cheaper) alternative to the HPA switchable controller. Reliability of the haldex clutch discs has always been my concern with it I guess.
