Bruce, thanks for posting - and good to hear about your long happy history with the unit
The pictures of Thelma are indeed helpful - it gives a good idea of how the unit was mounted.
Could you perhaps elaborate on the electric actuation - how do you shift the OD, when is the OD disengaged automatically (if at all), what happens to the OD at gear shifts (2 <-> 3) etc. That would give me a good idea how its wired
Thanks!
