The clutch in my '84 K10 was rattling so bad you couldn't talk to the other person riding with you or hear the radio. That and it flopped back and forth like a dying fish. So, I decided to dive in and fix the darn thing. This only applies to the linkage style clutches, not the later hydraulic type. Although there may be some similarities. First: Remove the gauge bezel. Next disconnect the speedometer cable from the back of the gauge cluster by lifting up on the retaining tang and pulling the cable straight out. Now remove the gauge cluster. Depending on year and options, there will be different things to unplug from the back of your cluster. Mine had the main plug and one warning light bulb that had its own wire. You should end up with this. Unhook the clutch pedal return spring.
