Question concerning fit of front brake rotors
Grassy I cannot tell for sure if your brackets (adaptors) are correct or not. You put the rotors on the spindles, put the pads in the calipers after retracting the piston if necessary, and slide the caliper / pads together onto the rotor and into the bracket.
If you look at the last photo Okla posted You can see the stamped steel retainers (anti-rattle springs) installed on those brackets
