A quick update on this project:
The engine was rebuilt over the winter and installed a few weeks ago.
I also rebuilt the gearbox, while it was out as the bearings were showing signs of rust damage and put new UJ's in the propshaft.
Yesterday, I started and ran the engine for the first time, sounds nice and smooth. Took the car out for a few short test runs, all OK but the back axle has a horrible growl on drive, quiet on overrun.
I suspected that I would find endfloat in the pinion shaft and I wasn't disappointed. About 3/8"
Pulled the torque tube out and dismantled it today. Input flange was loose on taper, spacer was very worn, the nut was still tabbed up from the factory but the spacer measure 1.095" and it should be 1.125"!
Sadly, the car must have done a few miles in this state as the pinion has picked up at the back end where it was being wound into mesh too deeply.
I'm making a new spacer from a piece of scrap steel, I'll put it together and see how it sounds but it ain't gonna be quiet!
