Hello! New user here, and long time lurker for this website.I've come across an issue where there is a strange scratching noise coming from my speedometer. I've pulled the gauge cluster out and tried to lube the speedometer cable with some white lithium lube, but shortly after I took it for a drive, the noise came back. However when I press down on top of the dash with my free hand, the noise goes away until I let go and starts happening again. I drive a 1980 camaro, everything is close to original as possible if it helps. Any ideas are welcome!
