8.75 disc brake conversion kit without parking brake

I guess I'm wrong Wilwood does make a kit that MIGHT fit in a 14" steel wheel.
Wilwood Disc Brakes - Rear Brake Kit Part No: 140-11386-DR

But man that is a lot more braking than I really need for the rear of the car. The only one I know of for front brakes is the Scarebird kit and that uses a 11.75" Cordoba rotor and Chevy single piston sliding caliper. The brake balance wouldn't be very good I don't think with the Scarebird kit up front and the Wilwood kit in the rear.
