leaf spring diffs obviosly wont fit a coil spring diff.XD leaf/XE&XF coil(in sedans) disc brake stuff won't bolt on to a drum brake diff i'm98%sure
about the only thing left is to hope someone has done what you want to do(as my brother did) and upgrade then to a 9" so they are selling the B/W
or for the best part of a grand you could see a diff bloke and choose any raio you want
3:23 diffs cam standard on all 3.3 litre falcons on XD/XE and XF's, as the 3.3litres lacked power so the 3:23 diff provided the "get up and go" that the 4.1 litres have. its just hard sourcing one, as I want to get one from a disc brake setup to match it with mine, all I need know is everything going to be the same if I use a drum brake diff?
and also 3:23 was optional with all falcons, a lot of manual xf's got 3:23's, but there wwas unfortunetly no 3:23 LSD on XF's.
so does anybody know if I can use a drum brake 3:23 diff for my disc diff setup?
