XF diff need help
Im after a few ideas on what i should do with my 2.77 LSD in my XF Ghia.I want to up the gears to about 3.45 but dont know what diffs might fit and if i should go to a nine inch. Idealy in the long run a nine inch would be required but do earlier model nine inches fit in the XFs or do i have to have one custom made. Another option that i have thought of is and LSD from a later model falcon but do any of these fit straight under or not. If anyone has any ideas it would be appreciated.
