I can't answer your question on the CWP sizing and casing differences, but I have a Stag differential torn apart and was working on my TR6 differential this past summer.  The cases are different at the rear cover and the gasket and rear cover for one will not fit the other in one corner of the case.  Since the diff casing is a structural member of the Stag rear suspension subframe, you can't simply exchange one diff and casing for the other since the rear cover won't bolt up.
