Is that a standard Petrol M66 AWD diff ? Supposedly from S60R M66C, right?

From your story it becomes clear that the 45-spline-to-angle-gear petrol M66 diff paired with the D5 final gear ring without issues. Is it so?
With all this effort you got M66 with wide diesel gears and 4:1 final drive + 45 spline output mounting the P80 angle gear without worries... Brilliant.

Last thing - interestingly, if it is possible to interchange the XC final gear pair into AWD housing ?
