You have to have a drum brake spindle and hub to do the mod. There is a couple of write up online for doing it to a Camaro.

You'll first need 5x4.75 bolt pattern.

Possibly turn your drum hats to fit the rotor hat.

Set rotor, and caliper on your modified drum hat.

Then you have to use 1/4 quality plate steel, and cut it so it sits where your backing plate once sat. Then you can bend or cut and weld your way to where the caliper needs to be.
