XJ6 Differential

Alright, I am restoring a 1973 XJ6 and want to place a LSD in the rear. I know that most XJS' have similar components and was wondering if the I could use the DANA LSD from a 1986 XJS. The XJS is 2.88 and the XJ6 is 3.54 gearing. I'm looking for a relatively simple swap that isn't going to be too expensive. If you guys have any suggestions or information let me know. Its a Series I XJ6 obviously. Ideally I would just take the rear end of an XJ12 but that isn't an option as of now.

No, 3:54 was not a standard XJ6 diff.

Don't take mine as the final word. I'm thinking the Dana will bolt in but I think you'll need to get the brake rotors that go along with it.

As far as I know USA Ser I cars had the 3.31 diff.
