1970 and newer take the same knob as the one pictured on your lighter. 2 year only knob for 69 and 70 is the lighter. Your wiper knob is pre 70. I have knobs , Mint knobs are not cheap for some wiper switches. They have different Dia. holes for the switch being used , That is where most are different as are the washer style. Note the radio knob felts that everyone loses. Where is the small rattle coming from. LOL
