I have looked thru the Ford manual but I cannot find the master cyl bore dia. 97 Ranger 4cyl 5spwith power brakes. Can any one help? Did that truck ever have non-power brakes?

They had power brakes only. For the bore diameter of the brake master cylinder, try RockAuto. When I was looking at various clutch master and slave cylinders, they often included the diameter in the part description.
