I did the Scarebird conversion about 5 years ago when they first come out with it. I just bought the plates and sourced the calipers and rotors from local parts house. I have less than $250 in the complete swap and haven't had one problem with them. I didn't change the proportioning valve they recommended but did use a non power disc brake master cylinder and my Cuda stops straight and true from any speed.With low to normal pedal effort. Highly recommend this swap. Only thing I wish I had done was to drill hubs for the 5x4.5 bolt pattern, so now I have 5x4" with 14" wheels in front and 5x4.5 with 15" x 14" wheels in back
