maybe something adapted to a different engine.. 2.6 or something even more exotic out of africa or something. Who knows (someone on this board for sure) From what I see, they all use the same flywheel (at least the same diameter) and there's not enough room for a variance the size you mention in my flywheel housing. About ... oh .. just a few mm from teeth to housing.
I was under the impression from reading that the II IIA IIA-H and III were
near identical in and out. I've read a lot about people swapping them back and forth... no mention of new flywheel housing. Just clutch parts and double clutching. (Which brings up.. I hope this tranny is from '66+)
But you never know what people assume you already know I may be in for a big surprise.
Getting excited. Its a mystery!

here Seems promising
Gearboxes:
" All gearboxes are interchangeable, though there are two types of bell housing stud patterns. The early pattern was used on the 1.6l and 2.0l engines. Swap the bell housings to fit the engine and gearboxes together. The later bell housing started in 1958 with the diesel engine, and is still used on current turbo diesel Ninety Defenders and Discoverys.
There are two types of clutch mechanisms used. The earlier was used for the Series I through Series IIA, while the later started with the Series III. The former is a more complicated system with external linkages, while the later uses a simple arm within the bell housing."
