Purchased this rear in 1991 thru Philadelphia Penn Jaguar in Bryn Mawr, PA. This rear has less than 30K miles of use.
They installed it in my 1987 XJS coupe V12. I also replaced the GM Auto transmission with a Getrag 5-speed manual transmission. Before I sold the car in 1996 I reinstalled the original 288:1 ratio stock rear.
I don't believe there were any significant changes in the XJS from 1983-1991 so this rear would work with most XJS’s.
