Looking at the page Serge posted in the first message. it looks like the adapter is inline (possibly threaded to the input of the speedometer) rather than inside the speedometer.
Perhaps my first attempt at explaining what I though was designed here was not clear. I agree the information for the speedometer is taken from the rear of the transmission. The speedometer drive gear is clearly shown at the rear of the transmission in the maintenance manual. With the two speed axle being between the point that the speedometer gets its information and the tires, it is possible to have two different road speeds for one indicated speed. To correct for this the speedometer adapter would have two ratios (probably direct and 1.391:1 so that there is only one set of gears involved), different from each other by the same ratio as the two ratios in the axle.
