I have a parts book showing the upwards facing lever, [that is with the cable clevis above the cam] the number for that is 42-6353 although no year is mentioned. The backplate for this one is shown as 42-6357 and has the bolted type "cable outer clamp" if that helps.
A different parts book shows an upward facing lever as part number 42-6317, this goes with the backplate with the cast in cable clamp. part number 42-6314, so if your backplate has the "clamp" cast integral with the backplate, you need 6317.
