Can I use the drum brake hub with my disc brake setup? If so, then I shouldn't have to replace them - they were in good shape when I redid the bearings and brakes about 12 years ago. I've only put about 5-7K on the car since then.
There's an aftermarket package that uses the 10" drum spindle. That comes with its own hub. I beleive it uses standard disks.
For switching to a factory 4 piston caliper, you need the disc brake spindle. If your disks don't have hubs, you'll need them too.
As far as distribution block to go with a tandem master cylinder, there were several flavors. The earlier versions are used in conjunction with a seperate proportioning valve. The later ones combine the proportioning valve.

Remember your rear drums will still be the pre-69 flavor, so don't use the '69 and up bulletins for reference on those unless you change automatic adjusters and shoes to the '69 style.
One last tip. The "edge code" on the pads and shoes will roughly indicate the friction. Take a note of those in case you want to make adjustments or keep the same. DD is typical, EE is better, FF is good. These are broad ratings but they are to an SAE standard. Material will also effect how they feel at different temperatures.
