Just curious.

Doug, you couldn't possibly know this, but the original poster's (Jim Harding) problem is a bit "unique," no pun intended. Jim's Unique was built in 1982, and needless to say, his Jag rear-end lasted quite a long time.
The reconditioned Jag rear-ends used on more recent Unique's are done on model numbers with parts that are readily available today. It just so happens the parts used on Jim's particular now 25 year-old Jag unit are difficult to find today.
However, I can't remember the last time I remember reading someone needing to have a Jag rear-end rebuilt on this forum. Now if you want to talk about expensive, it's the big block FE that usually does people in. The Jag unit is the last thing you should be worried about.
Jag rear-ends are used on the higher end Cobra replicas because they are virtually identifical to those used on the original. ERA uses them, and even Kirkham uses their own knock-off of the Jaguar IRS rear-end design.
