Suspension, Brake Shoes and master cylinder for 65 Cuda'

I began to rebuild the front suspension on my cuda with the PST rubber kit. Decided to keep the stock drum brakes with new shoes and wheel cylinders. I plan to replace the master cylinder with a 2 port type and necessary proportioning valve. Drums measure 10" across, having a hard time finding shoes to fit. Are these unique shoes? What decent master cylinder will fit with a minimum of fussing? Also Prop. valve recommendations would be great. Thanks in advance guys!
