Hi Rich,
The big coil spring that sits between the control valve lid and the diaphragm is a modification spring. It was never part of the original Lockheed design but problems with brakes sticking on later showed this to be a design fault, so to compensate a modification spring was added.
A new control valve sounds like the way to go, everything is included save for the modification spring which you must transfer.
