1962 Other Buick Models Disc Brake Kit for a 62' Buick Speci

I'm having a difficult time finding a front disc brake upgrade kit for my 1962 Buick special. There must be a way to modify this or? What if I replace the part holds the brakes on. What's compatible? At some point GM must have had to have standardized something or some part of this assembly, no? I'm lost. I love this car.
Thank you,
