Ha Ha Ha, the question should be “has anyone ever done ANYTHING to a (fill in the year of choice) without any complications?
In all seriousness it is “relatively” uncomplicated if you assume that the existing brake lines are 70 years old (and/or were worked on by someone under qualified) and that they are very happy not being worked on, and that this will be a great time to remove and replace ALL of them including flex lines, and ask yourself what condition the brakes, wheel cylinders, drums, etc are in.
Once you answer those questions, yep…no complications.
There is a good video on YouTube of this exact dual master install done by Brothers Trucks, Welsh is a real deal mechanic and he walks you thur the process. He does a R&R in a couple of hours….but he does it every day….search YouTube “1947-1959 Chevy dual master cylinder upgrade” it will come right up…
Ps: good,time to buy a Motive pressure brake bleeder……
