I don’t know if anyone can confirm the XJ side for me, but I’m curious about bell housing to yoke lengths on AW4/231 vs A999/207.

What AI tells me is:
AW4/np231 - 46.5”
A999/np207 - ~45”

Going from A999/207 to AW4/231, I figure if I drop a SYE in the mix I’ll still be able to pick up a couple of inches on the rear driveshaft.

Any confirmation on AW4/231 length to be had out there? I’m not totally convinced that AI has all the facts.
 
AW4: 25.375
A999: 22.625
NP231: 20.5 w/stock output.
I was including reference pages but then my damn phone browser dumped what I was typing so I am lazy and do not want to pull them all again.
I was not able to find a solid reference on the NP207 but you can measure yours (post up so it is documented).
