4 wheel disc master cylinder?

Are there any options for a 4 wheel disc master cylinder for swaps? I am on the verge of ordering a Wilwood rear kit and got to thinking about what the options are for a master. What have you guys used or heard of being used?

1987 dodge diplomat or 87 Chrysler, works pretty well, maybe a hair more pedal pressure than I`d like, but they are manual brakes!
