I will try to make a post later on about reworking a Jag differential and replacing all seals (mostly for BiTurbo's use). It will cover the friction plate setup in the Power Lock, so Jeep guys with Jeeps may be interested as well. The plate thicknesses weren't covered anywhere I could find, but I was able to get information elsewhere that may help some people.

If anybody but me (and BT) ends up doing a jag suspension project, this may come in handy.
