Need a console shifter bar for my 66 cuda

You can use the 68 & up hurst style but you will need the console shifter handle (bar I believe you are referring to) & a hurst box. the 68 & up handles are available as reproductions from brewers. they are a bolt on handle & do not say hurst on them. The 67 & older are not being repopped yet as far as I know.
