I believe the proportion valve goes on the rear brake line to limit the pressure to rrears as to not get rear lock up, and equal brake bias for correct stopping.
If you switch from rear drums to rotors I think it is based on the thickness of the rotor where it goes over the axle hub, which should be very close to the thickness of the drom, just slightly thicker, in the thouanths range. That is my take on it. I do not think it would be a problem. Hope someone who performed it already will chime in.
