Hey all! New here but been surfing for ages, so my hz one tonner built is 13 years in the making and it come crunch time for installing the instruments.
So turns out I have a HZ body and chassis, HX body harness and late HJ gts dash.
So I've found out the hard way that the 3 don't work together as the wiring is different and also the speedo, and some bulb locations. Obviously the easiest option would be to get a hx dash but I'm not in a position to do so.

So what are my options? Is it possible to get the hj gts dash assembled to work with the hx body harness amd dash facias and if so what's involved?
