Well, The Series 2 Jaguar Differential was on the XKE from 1964 thru 1974 as well as the 1965 thru 1983 Jaguar XJ-6. Sometimes, the year code is punched in the casting on the lower right corner of the cover. The year code is the top number on the cover. These are getting to be harder to find now.
Also, there is often a small metal tag present on one of the rear cover bolts. This tag has numbers on it. If the tag says 43/13 then this means it is a 3.31 ratio gear, 43/54 means 3.54 and 44/11 means 4.11 gears. This tag is not always present due to maintenance. Jags XKEs in the 1961-64 time frame almost always had 3.31 gears but then to meet emissions standards in the USA, the car was detuned, lost torque, and so to keep the feeling of performance, the rear gears were changed to 3.54. Those are often found in 1964-1970 rear ends. Some of the automatic cars had even higher ratios. That is about all I know about this.... Does anyone else have any more info???
The series 2 rear typically has inboard brakes. I have been told by some Jag experts, that there are some variances in the brake holes in some rear center sections. I am not well versed in that aspect. These rear ends can take about 500 BHP, however the drive shafts and such have to be in good shape to do that. I would never suggest poping your clutch with really high RPMs and a hot engine. There are some horror stories here with blown components in the rear from such misbehaviors.
