Wow great read but still quite confusing for the novice. Have just picked up a hj ute with a 308 with a ford 9 inch diff and disc brake rear end in it and have noticed quite allot of others have had the same conversion. should I keep it or should I chase up the GV7 diff and axle as I would like to have this as original as possible? My mate was pretty quick to offer me some great money for it and chase be up another diff. What would you do?
