There are several sources for kit the kit from, master cylinder for disc brakes or drum or disc frt/drum rear. You can buy parts salvage and modify to fit. There was a you tube titled Idaho Fabricator who has a detailed install for AD truck cab. I hope the video is still up he died some months ago but last time I checked his videos were still up. Well worth the time to check it out. LS motor swap, suspension swap, modifying all that was needed brakes etc....great videos.
