1968 Barracuda Console shifter and 1st gear

Do all of the factory console shifters have a 1st gear position?? Can they all be manually shifted into 1st?? I'm having a problem getting mine adjusted to be able to manually shift into 1st. Am I missing something here
Shifter knob should look like this (or center knob a bit higher) when in Park or Neutral to allow shifter cable to enable you to shift to 1st gear...MD4012.jpg
