no mate there not the same you can use them but you will need to mod your inlet plenum as the lug on the plenum next to the fuel reg is in a diforent place and you will have to sort the reg out as well

in this photo its a 4x4 plenum with a 2wd rail you can just see its got 3 lugs on it the very front one is for a 4x4 rail and the second has been adid to fit the 2wd rail hope this helps you some
