Hydroboost not working. Please Help!!!

[GBodyGMachine]

I have been fooling with this for about a week now. First it was a bad master, then pump, then a bad hydroboost, today was leaky lines.
Finally got the car on the road and all seemed great for about 2 blocks.
First thing I lost power steering, went to hit the brakes and the pedal went to the floor. Then everything came back for about a block and then when I applied the brakes they stayed applied. O, then the pump started to howl.
WTF
Hydroboost, master, and pedal assembly are from an 85 GN. Pump and Gear box are from an 84 GN.
Any help would be excellent. I am out of ideas.
