Thanks gerg and chestnutxe, very informative. I appreciate it. It seems i will stay with the 4 spd top loader, will now have a five spd for sale. So if the diff ratios from the xg are too low would the diff centre in the xd fit that housing? The ute cruisers at around 2000rpm at 110ks now, so when i fit the xg rear end it will rev higher.
Another question please, will the brake booster etc from the xg fit the xd?
