Today seemed like a nice day, so I figured I'd pull my instrument cluster to figure out why my dash lights wouldn't work. Checked the leads, they were in surprisingly good condition; PCB leads were all intact; bulbs were still good. So I go to check the rhesostat to repair it (used the DIY article by tankowner), and lo-and-behold, I find: this:





The spring was sticking out when I took a look at it. Upon disassembly, it looks like this. Dunno how long it was like that, but I figured years of turning the dial arm against it out of the channel did it in. Safe to say it's pretty fargone to repair. Any ideas?

PS: Lost one of the two counter-springs in my carpet
