I have a set of 3 meters that I bought a few years ago, and now am finally thinking of putting them in the car. They are k's meter works, oil and water temp, and oil pressure. I have been looking online, and cant find any real info on them, or anyone that has a set. are these super rare,, or just super cheap so no one uses them?

 

They're available still, just not usually in the US, that would make them somewhat rare.

I'm curious what version you have. Can you post a pic?
