I was going to pick these up, but couldn't get a reply from gaugegear regarding some installation questions I had. (emailed direct, tried a PM on this site... no luck) I finally had to pick up some under dash gauges as my engine was in and about to be fired up. I may look at adding the gaugegears down the road.
What did you need to know? It's a pretty straight forward installation. I may still have the instructions.
