Jack,
Does the BBK cable then come with just a stop on the pedal end instead of the normal ring end? Do you have part numbers for the BBK cable, quadrant and firewall adjuster? I have broken 1 cable, and the pedal has rough spots in the travel as though the bushing is gone (there is no bushing on the cable mount - it attached to the pedal with just a bolt). Had to drive it home about 15 miles with no clutch - interesting when you have to stop
