Hurst Competition/Plus shifters have been the benchmark of transmission control and race-proven since 1963, and still today are constructed using the same high standards that George instated back then. Hurst Competition/Plus installation kits are custom designed to fit directly into your vehicles, with the least possible modifications, and to give you firm positive shifts every time. This Hurst Competition/Plus installation kit fits 1969-1979 Chevrolet Corvette applications when using a 1969-1974 Muncie (452, 453) 4-speed transmission or 1974-82 Borg Warner Super T-10 4-speed transmission. The kit contains everything needed (shifter not included) to install your Competition/Plus shifter and to operate the above transmissions. Note: 1963-1968 Muncie (451) transmissions use a stud (with a nut) coming off the shift fork of the transmission to secure the shift arm to the transmission and will require a different installation kit then this one. This installation kit fits the following vehicles with a Muncie (452, 453) or Borg Warner Super T-10 (454) 4-speed transmission: 1969-1979 Chevrolet Corvette
