I located a wrecked Jag X-type thats AWD.... but its an automatic.... BUT I can get both front and rear sub assemblies for around $500.
I really need some measurements off of the Jag's rear sub frame.... depending on how much wider it is I could always do a custom "wide fender" setup on the back.
As for biasing everything.... I'm still working on that one, but I do have a couple of idea's.
Personally I think all Jag may be the way to go.. if you find just one AWD 5 speed thats wrecked all of the differentials will have the correct gearing ... one less headache
Edit: luckily I DO have a lift
