I got one in my 71 dash that I will never use. Only problem is how do I blank it off so the nasty hole os gone and how does one disassemble it?. If someone can answer this then Stuart can have mine for $20 shipped to the US. I will run it through one end of the scale to the other on an ohmeter first to make sure it works good. But my dash was stored for about 20 years before I got it and so far everything electrical works perfect. I can send you pictures this weekend Stuart after I get back home. I presume you mean the fader switch?
