Well I found my k style differential !! It was long shot but I found it ! That's the good news but the bad news is that my axle casing which I thought would fit does not. As I am learning, I've been told that mine is most likely from a Wolseley 16/18 and I need a Wolseley 14 or K type. The differential case which bolts to the rear measures 9.25 while mine is slightly larger at around 9.75 - 10" . Any thoughts or assistance ?? As always, thanks Dan
