Can anyone advise on a source for a rebuild diff kit, a rebuilt diff or a replacement diff for my 1984 KE70 origionally fitted with a Borg Warner T669-42-019 ratio of 4.30 Service no 6375. I understand that I can drop the ratio to 3.9 but cant seem to find either option, none left in wreckers yards locally or interstate. I am situated in Central Queensland near Rockhampton. Thanks for any heads up.
