Years ago I found a site that identified what model Jaguar my Differential came from. That site has disappeared. I've done a search on this site and found nothing. I've contacted many Jaguar parts companies and they want pictures. The only other identification method was the width of the rear end. Not much good when it's been narrowed. I messaged the Jaguar Owners Club and have no reply. I've even just punched in the cast numbers and stamped numbers off the diff an had no joy. Can anyone help me here ?? Surely there is a document somewhere that identifies the factory cast numbers and conforms the stamped ones. A mate needs to know what his diff is so he can replace seals.
Can anyone throw some light on this for me ?
