That master cylinder casting number you listed is for a 1-1/8" Raybestos/Napa United master cylinder. I assume your car is a '70 disc brake car? If that is the case you are looking for a 1" diameter master cylinder with casting number 2229171. Unfortunately this was a one year E body only part, so they are not easy to find and not cheap when you do find one.
The casting numbers on the calipers sound right, but I'd have to crawl under my car to check. AFAIK, no aftermarket company ever made calipers for E bodies, so any one you find is either original or a rebuilt original.
