That stack install is the nuts, that is exactly how I would do it, but I would probably go for black to match my gauges, like you have.
My rev counter is well out, the other night it read 6k and the car slowed down, changed gear and it was ok... hmmmmm... 800rpm out then lol. I think that after my boost controller is bought (whatever I go for) I will have to invest in a decent rev counter.
"Ahh... I love it"
When you going to bring it out?
