This is what you need. 10# residual to the rear, as close to the MC as possible, with an adjustable valve. Do some research so you know how to set it up and test it. 2# residual to the front, as close to the MC as possible. Run a single line to a metering valve. The metering valve has three ports, one in and two outs. One is for the right and one is for the left. Bleed your brakes and you are done.
