still getting familiar with my 82 Interstate. I notice the speedo/tach cluster seems to move, like its only attached by the key lock cylinder at the bottom center. The top of the cluster moves back can forth. Is this normal>?? Also, does the speedo cable just unscrew from the back or do you have to remove the speedo? I just heard some whinining noise starting, started suddenly. I read on forum to lube the speedo where cable attaches. THANKS
