The
1965 Corvair Chassis Shop Manual - SECTION 12 - CHASSIS ELECTRICAL (attached) addresses removal and installation of the instrument panel starting on page 12-10. I have also attached a copy of the section from the
1965 Corvair Assembly Manual - INSTRUMENT PANEL that describes the instrument panel installation.
The odometer is driven by an internal gear assembly that may be worn out, possibly due to a lack of lubrication from aging grease. A speedometer shop may or may not be able to repair this. Alternately, you could try buying a used speedometer on eBay or from a source like the Corvair Ranch in Gettysburg, Pennsylvania. I have attached a CORSA magazine article that describes a similar problem and repair on a Corsa gauge, but you might find it to be informative even though you have a Monza instrument panel.
If you do buy a used replacement speedometer that is fully functional, it might be a good idea to send it to a speedometer repair shop before installing it to have it inspected, serviced and lubricated (after all, it is about fifty years old!)
If you need replacement components, I would suggest contacting the Corvair Ranch in Gettysburg, Pennsylvania. They have been providing Corvair owners with good used parts for many years and they have a large inventory. They will know what questions to ask to ensure that you get the correct parts.
