That enclosed rear tranny cover has exactly the same bolt pattern as the CMP part.....so must be interchangeable. So a civilian tranny can be converted to a CMP model with the special CMP open drive shaft cover...... and the speedo gear location is the same..... possibly the part from a civilian speedo gear would also interchange.....

From the enclosed picture you will see the two different models I have come across..... the early model with the fully machined speedo gear is made of very light white metal of some sort.... the later war production are cast steel and the speedo "boss" area is not finished of machined as the speedo gear was fitted to the T-Case.....but they all suffered the same destruction when a yoke bolt worked loose and sheared the mounting bolts and parts of the rear cover...... finding a good rear cover can be a challenge and adds value to the old tranny.
