I bought this kit. Uses stock drum brake spindles and bearing hubs. Uses floating rotors from 1991 gmc 4x4 and 1998 astro van awd callipers. With the part #s all is available off the shelf as well. A little pricey but works well and you don't have to completely disassemble your suspension. If you want to add brake shields you can modify 67 70 car shields to fit.
I did it in my build thread.
