If u suspect u have the later(1980 and up) calipers,u can measure the Pistons. The older calipers has a smaller piston2.910 vs the later model caliper piston at 2.940. Rr is right about the casting. Also the newer calipers look the same so u could have gotten the wrong calipers n the box when u ordered them. The pads have the same shape and length, but as u have found are different n thickness. That noise u have is the pads grinding against the rotor. They will ruin the rotor if u have the semi or metallic set of pads as they are harder that the cheap organic pads.
