00 and 01s have the LP D30s.
Most other XJs have either the 8.25 or the D35 (87-89 with towing package might have a D44)
Most are also either geared with 3.07 (manual) or 3.55 (auto). All 4 bangers have 4.10s.
The 8.25 did NOT come with the XJs with ABS. If you have ABS you have a d35.
If you don't have abs you can have either. Get under there and look. Post pictures and we can judge it.
97+ XJs have 29 spline shafts and 97- have 27 spline shafts. (In reference to the 8.25) The change over year was 96. The only way to tell is to count the splines
D35s have 27 spline shafts as well but the 27 splined 8.25s are stronger than the 27 splined D35s.
Also note some of this may not be 100% correct, so before you take my word for it search search search.

Thank you!
Would fix my Original post, but it would just confuse everyone. Here is a totally fixed version that is 100% accurate according to everyone in this thread.
I am currently throwing a website together with all this information to organize it all in one place. Tell me if this looks good and accurate? Don't want to be spreading false information. Currently updating this exact page just need to find the picture i'm looking for.

97+ XJs have 29 spline shafts and 97- have 27 spline shafts. (In reference to the 8.25)
However, Some 1996 models were built with random parts. Late build '96 may actually have a 29-spline, and the only way to tell is to rip it apart and count. -salad
D35s have 27 spline shafts as well but the 27 splined 8.25s are stronger than the 27 splined D35s.
Factory Gearing;
3.07 - used with 4.0L engine / manual transmission
3.31 - only available on older (pre87?) 2 door XJs with "Fuel Economy" package
3.55 - used with 4.0L engine / automatic transmission
3.73 - found in some older XJs with the towing package
4.10 - used with 2.5L engine usually, and older XJs with the "Off-Highway Vehicle" package.
4.56 - rare but can be found on some older (~ 89 ~) models with 2.5L engine and auto transmission
Only manual 2.5L gassers had the 4.10 gears, automatic-equipped models actually rocked 4.56s. The 4-cylinder diesel engines came with the same transmissions as the 4.0s. -salad
