Disk Brake I.d. Help

[HemiMark]

I just bought a 1970 Duster that was changed over to a 360, front disk brakes, and a 8 1/4 rear..... front and rear are big bolt pattern. Now how do I ID what brakes are on the car? The numbers on the calipers are....
950204 or 95020A. There is also a 3 digit number... 771 Any thoughts?
