I recently purchased a power disc brake conversion kit from chockostang. My 1968 Mustang originally had original drum. I found that my brake support did not have the unique hole to mount the new pivot point for a power brake pedal. Chocko sent me a new mount with the correct hole, but I cannot figure a way to exchange the mounts. Does the instrument cluster have to come out for this? Steering column? Any help is appreciated. Thanks
