I have restored numerous 65/66 clutch/brake pedal assemblies but this one has me stumped. The physical dimensions of both the clutch and brake pedals are identical to what I know to be original 65/66 clutch/brake pedal assemblies. This one has a stud welded to the pivot point of the brake pedal. It is 1 7/16" long, 3/4" wide and 3/16" thick. It definitely appears to be a factory weld. Does anyone know for what application this one could have been used?
