EDIT - UPDATE -
OK .... Early morning and nothing better to do ...
There was a 63/64 FAIRLANE 170 that came though with a 3.03 3/S.
The bell was unique - Casting I.D. - C3OA 6394-B - Service PN C3OZ 6392-B
Flywheel - C2OZ 6375-D (160T) - Takes 9 1/2" Clutch
So if it will take a 3.03, it will also take the 3/S WARNER OD or even better yet, the later TOPLOADER F/4/OD as a money saver over a T5 conversion.
I bet this is what the father did W/3/SOD and maybe instead of an OD cable used some kind of make-shift lever (maybe).
This is for anyone that is looking for this info in the future.

Yes, I remember I had a lever that I needed to put into overdrive mode. This took the compression out of 2nd and 3rd gear so if I took my foot off the gas while in those gears the engine would just idle even though it was in gear. In this mode, I could take my foot off the gas for a second and the overdrive would kick on and compression would return in OD gear. I also had an electric switch I could flip that took it out of OD and back to regular 3rd gear.

the Econolines, due to their mid-engine design, have a shorter than normal driveshaft. Anything shorter than stock could put extra stress on the u-joints. If you do shorten the driveshaft, you need to ensure proper geometry between the transmission and the axle.
