I made the same search for disc brake options for our 1965 Ex Military F-100 restoration. Because we will be towing a small custom Camper trailer I decided I wanted the kit with four wheel Disc option. So I ordered the full kit from Classic Disc Brakes. Sadly It was a bad decision and we are very frustrated and disappointed with our choice. We ordered the full kit at the end of June and we still do not have all the components. The company is small and the parts are custom to each application. They are understaffed and over booked. The documentation or instructions for installation and maintenance are almost non existent. The parts have come in multiple shipments with no tracking numbers and no packing lists included. There have been quality issues and we are still waiting for mounting brackets that required replacement because the originals did not fit. That has happened twice. When we try and contact the company, we get endless recordings and never get to a real person. They over promise and underdeliver, quality is not what I would expect and they consistently miss promised ship dates. If I was not 2/3 into the brake install, I would cancel the order. But they also hit my credit card for the full amount 5 minutes after I placed the order back in JUNE. My recommendation would be to stay with a better known AUTO PARTS supplier that can provide front disc equipment off the shelf and forget the rear disc equipment.
