K989 diff, untested

K989 diff mockup
Not printed and not tested
this was a request to try and model one
couldn't be bothered to strip a car to do it - but had a pair of mini z diffs I cannot fit till my longer dogbones arrive - as the K989 diffs have longer drive cups

measured a miniz diff for the body, and roughly measured the cups from a K989 whilst it was on the car (so plenty of scope for errors)
I would not expect the gear to mesh at all - I struggled to get the measurements required and I doubt any of my printers would be capable to actually making anything that would work (all my printers currently fitted with 0.8m nozzles)

Comments are welcomed if you actually print one - but again
I have not - and will not print one and this is just done from as close a dimensions as I could manage...
