OP is from South Africa. His profile shows a '98 Ranger.
slysai: Welcome to FTE! Your sump from a Fairmont should be a dual sump, right? So you will need either a front or rear, depending on how things lined up.
A little search shows the South African Fairmont GT to be the same as the Australian Falcon GT. These are unrelated to the Fairmont sold in the US. The engine should be a 351C. So, you will have to figure out your sump needs, and you may have to get a custom or aftermarket pan, as I doubt the scrap yards are full of this type of engine in your area.
