ANSWER: It is possible you have a problem with the master cylinder or the push rod adjustment between the master cylinder and booster. It might be adjusted too far out causing the brakes to drag.
Also, I hope you used the master cylinder for disc brakes because a drum brake master cylinder will have a residual check valve that keeps some pressure in the line.

Answer
I don't have a part number for your paticular application, but it you get a master cylinder for an AMC with disc brakes that will bolt up to your booster, that should work. Do you have the one from the 82 Concord? That may work if it will bolt up to your booster. Check the routing of the brake lines, also. Make sure the line going to the front brakes is in the proper side of the master cylinder.
