Thanks for the above everyone - and noted on orientation of driveshafts, circlip, and the need for the installation ring for the diff seals.

Just to clarify - will there be enough room to install the gasket between the diff and oil pan once the diff is loose (videos seem to shoe sliding the diff down to access the alternator bracket. Not full removal out fromnunder the car….- does it have to be (and can it?) be removed out from under the car/is there enough room to do this - or can it be wiggled around enough to reach in between it and the oil pan to install the seal?
