I think I'd be tempted to buy one of the GM Generic's for disc/disc and see if that might fix your problem. Also questioning that banjo fitting with the very small port.

I have 2 new ones, 1.125" and a 1", corvette types . I wonder if the out put is different on the Generic type as in equal amt of out put fluid ? The ones I have have a 2 to 1 out put, the 2 going to the front.

With all my testing including the last one with a proportioning valve from the junk yard I believe some how I have to increase the pressure to the rear caliper.

Navy, I believe you need to increase the volume to the rear, just my thoughts. I know its frustrating in a situation like this but volume and pressure are different and on brakes pressure can be held off but the mc determines volume not the valves assocciated with pressure. If there is anything to gain its you now know as i mentioned in the first of this thread there are many rods running around with no rear brakes.
