Hey, please give me a little help here.

It is my understanding that all Lancer Evolution VIII and IV models in the USA come with ABS except for the 2004 Lancer Evolution VIII RS.

It is also true that only the 04RS has proportioning valves connected to the master cylinder. All other vehicles have proportioning control within the ABS unit.

Am I correct?

Would anyone know the part number for the 04RS prop valves? The dealer seems to be having trouble figuring this out.
