Round rear drive flanges...

[Sprint]

are they an ENV only kinda thing? or did the rover diffs on II/IIA's have round drive flanges too?

If you are referring to the drive member that connects the half shaft to hub, the original Landrover ones (front only on Series 1) were a six fingered spider. These changed to round ones, with the space between the fingers filled in, around the start of Series 2a production, independent of the type of axle. This was probably due to a change in manufacturing method, going from a forging to manufacture out of bar stock by machining.

If this is not what you meant, more details or pictures needed!

The layout is generally similar but the appearance is quite different, looking much more solid, and with a more apparent curve over the crown wheel. Probably the easiest distinguishing point is that on the ENV diff the pinion bearing carrier is attached to the differential housing by a circle of bolts larger in diameter than the tailshaft flange, whereas on the Rover diff there are fewer bolts in a circle about the same diameter as the flange.

ENV diffs, although an option on the 109 and standard on all but late One Ton Series 2as, are very rare, most commonly seen on the 2b forward control, itself very rare. I have never seen one except on a 2b.
