12. The speedo was free of the dash and as we removed the speedo from the "top" side of the dash, the rubber vibration gasket came off with it. We slid the rubber gasket from the stock speedo and reinstalled it on the speedo opening in the dash. We then carefully slid the new speedo into place, being careful to work the locking tabs (arrow) on the back of the speedo past the rubber gasket. A little squirt of glass cleaner works well as a lubricant.
