Hi On Purr Pose,
You need to define what type of tach you have. Remove the tach from the dash and get all the data on it that you can get; manufacturer, model #, serial #, range of rpm, etc. Then we can find where to get a replacement. Old tachs can be very difficult to find. Some aren't manufactured any more.
