rasko,... you've got respect, dude,.... not so many ppl spend their own time to make their own stuff these days,....
good luck with your project, and if you could just make it for all 6G models, i can help you to market it in South East Asia (as we don't have any white gauges for Eternas (6G galants) over here) ,.. maybe we can even find ways to integrate the blue glow-lights as well (who knows?!)
keep us informed
