They're just a straight swap over, should be able to do it yourself if a couple of blokes to help with lifting. Best bet is wreckers or ebay theres usually some on there. AU,BA,BF are all the same fit though the AU has different side moulds and I think skirts aswell but the tub is the same and the only difference between the BA and BF is the reverse light is in the lower bumper on the BA (& the AU) and its in the tail lights on the BF but the actual tub itself is the same on all 3
