When I was communicating with I believe his name was Mike at CWI, he told me the casting number were worthless for the most part. He wanted a physical description of the outside, seems a primary difference is the number and pattern of the reinforcement ribs on the outside. Below is a pic of the exterior of mine which turned out to be most likely from a mid-80s XJS with tapered bearings, and was actually a Dana. The way he talked, the only real way you identify them was open them up. The stamped tag bolted to the rear cover is helpful in identifying the ratio, as well as if it is an open or a BPL PowrLok diff.

Much better ..heres the pics. It is a posi and I do believe a
Dana Locker JAGUAR rear end with an axle ratio of 3.54-1

I just wish I knew what I was looking for when it comes to brake parts and options for such ?
like what year this is etc?

Solid rotors, Girling calipers, looks just like my E type series II setup.

[cobrajam]

See how it how it has the 3 thinner ribs on the drivers side versus the one really thick one on mine. I think that is what he described as being the pre 68-69 E-type. Looks relatively clean and complete, even the rotors look to be close to the full thickness.

[767Jockey]

Early "E" types (Series I) had the Dunlop calipers with the bolt on aluminum pistons in cast iron frames. These are the one piece aluminum Girling calipers, they're Series II pieces.

All,

I found information put together by Street Rodder and Mike Bontoft in April 1995. The scanned article is here: First Coast Cobra Club • View topic - Jaguar differential decoding

It's a pretty complete reference to identification of the various Jag/Jaguar rear differentials, brakes, axles and hubs.

Hope this helps,

Tom

Thanks alot Tom
Last question..if a guy needed brake parts ..would they be available locally or am I looking at ordering from somewhere?

An easy way is the front input flange on the Dana is the square one and the round flange is the Salisbury. Also the Dana Discs have to have two holes in them in order to facilitate removal.
