So I am thinking about increasing the stopping power of my brakes on my 1975 fleetwood 75. I am considering Delco 4 piston fixed calipers that came standard on some 1967 and 1968 chevy models including corvette and camaro (i think). Now would this upgrade be a simple swap? Or would it be more complicated?

Would the performance gains be substantial? Also I do know that the bore size of the single piston caliper that came standard for my year is 2.94 inches. What is the total area of the 4 pistons on the fixed caliper?? thanks For reference i have included a pic of each
