If you don't need to pass emissions, they should be functionally the same.

If you need to pass emissions I think there is a difference in the EGR passage between front & rear. Hence the different part numbers.

the rotors are the same so no trouble there.

with the rotor housing they only drill the air injection passage on one side, so if you want the other side, you drill the passage, its really easy
