I wrote the how-to, all surprises revelaed are explained in that. It wasn't bad at all. Buckshot and I did it in about 5 hours and that included a trip to the parts store twice after the double flaring tool busted
Parking brake works like a champ. Down to the balancer they are the same for drum or disc, so once you have a parking brake cable for a disc set-up just swap them out. Easy peasy. Were lucky because Ford used little reducer valves in the back instead of using a different design master cylinder, remove the reducer valve and boom you have 4 wheel discs with the proper amount of balancing.
