The drum speedometer on the '62 has brass needle bearings on both ends. The speedometer cable drives a magnetic drive wheel which is perpendicular to the pickup wheel on the drum. These units are good for about 120k miles until they need adjustment. What you do is take out the speedometer/instrument cluster by disconnecting the speedometer cable and the clock wire, removing the mounting screws and pulling the assembly out and inverting it on top of the dash. On the left hand side is an access hole covered by tape. Remove the tape and look inside. You will see a stop nut on the drum shaft and an adjustment . The goal is to move the drum a horse hair away from the magnetic drive wheel. This you can do by releasing the stop nut and turning the bearing with a very small wrench, then retightening the stop nut. Success. The speedometer will no longer bounce up to 100, it will be consistent, and it could be accurate if you road test the car and perhaps repeat the process.
