I'm in the middle of troubleshooting turning signal issues (https://classicbroncos.com/forums/showthread.php?t=303048). I've removed the speedo cable so I can access the turn signal bulbs; when I screwed it back in, the speedo stopped working. I've been looking at replacement speedo cables and noticed that the "key" at the driverside end of MY cable is not as long as the replacement cables. Is it possible that it snapped off and I need a replacement cable?
