Can some one identify what year my Ford calipers are from?

I purchased a set of front spindles rotors and calipers for a Ford mustang II (as advertised on e/bay)The rotors are approx 9.25 inches in diameter. The calipers are non floating and are single piston. They bolt to the spindles with a bolt on the front and one on the side of the caliper The front bolt uses a 3/4 inch scocket the side bolt uses a 11/16 socket if that helps. This set up is being used on a street rod and thats why i don't know the specific year HELP
