^^Agree^^ With Redfish.
The master cylinder shown here is not really correct

The disk/drum master cylinder has a larger front brake resevoir.

If your car has that master cylinder, rebuild it.
They have become very difficult to obtain.
Rebuilding it might be as simple as replacing the seals or it might have to be sent out for sleeving. All depends on the condition of the bore.
An alternative is to buy a aluminum master cylinder. "Dr Diff" is a reputable source and I assume he'll ship to Maui.
Be careful of the plastic resevoir - some friends had mentioned they sometimes leak at the bottom seal. They were a production item - I dont think its a major issue - just a weak point.
1968 is a transition year for drum brakes. be sure to reference '68 and earlier when working on the drums.
Front brakes and master cylinders remained unchange. You can reference '67 - '69, and '70-'72 is very similar.
Definately replace the hoses.
Everything else is a see what you find as you go along.
There are some excellent filmstrips and booklets on brakes in the '
Master Technician Service Conference - Chrysler's Training for Mechanics
Srcoll down to 1967 and '68.
With manual front discs, choice of pads and surface finish of the rotor can a make difference in how much pressure your leg needs to apply during a stop.
Yes a booster was an option, and actually a fairly common one at the time. But you may decide its not needed or even wanted.
