IIRC to swap you will need a T5 box, 2wd prop, diff, not sure about the front cradle, but deffo a 2wd sump, I assume you can leave the 4x4 steering rack on etc?? just run the 4x4 stub-axles on the front wheels and remove all the driveshafts/diff etc I am doing this at the moment so any more info would be great
