When you refer to the Jaguar differentials, do you mean the Cobra era Jags or modern Jags?

There have been some substantial differences over the years in the internals of the Jag diffs from the XKE to XJ6 and XJS such as open vs Power-Lok LSD and ratios that do not interchange, like the open XJ6 2.88.

As Tom says internals are interchangable with Dana 44 but you have to know what you are looking for.

Was there something specific you needed to know?
