I was part of the aus300zx.com group buy and have just cracked open my gauge cluster to find that the gauges don't fit. I have a 93 J-spec TT (series 2) and it appears there were some changes between series 1 cluster which I think you used as a template and the series 2. The mounting holes dont come close to matching up with my dials :( and I think the recalibration is completely different as well from what has been discussed on aus300zx.com.
