HI, the 7" diff in the pic isnt an lsd looks like a standard open diff to me!
I am happy to be proved wrong though.

The Sierra LSD are viscous so don't have the friction plates.
It has the Silicone fluid behind the "ring gear". It is a large flange that holds the "ring gear".
I never have dismantle one so I don't have pictures of it.
Bu I have pictures of a 7.5" open diff and you don't see the part.

Might make me look a right muppet but I always understood that to test if it's an LSD then turning one side will have the lsd diff spin both outputs the same way...non lsd goes opposite way...?

Hi Mark,
Yes that happens.

But the great question was.
Who can help me with these differential "two drive flanges"?

The flanges are not just a straight replacement, those slots for the circlips are there for a reason so you would have to pretty much dismantle the diff.

I am not saying they don't exist but i have never seen a Ford LSD with push in shafts
