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 will fit various GM vehicles when using a 1963-1968 Muncie (451) transmission, and contains everything needed (shifter not included) to install your Competition/Plus shifter. These (451) Muncie transmission can be identified by the fact they have a stud on the shift forks that secures the shift arm on the transmission with a nut. Note: 1969-1974 Muncie (452, 453) transmissions use a bolt to secure the shift arm to the shift fork of the transmission and this type of Muncie will require a different installation kit then this one. This kit will fit many GM applications and year ranges of vehicles, both with and without factory consoles and a 1963-1968 Muncie (451) transmission. Please refer to the Application tab and/or use the Vehicle drop down menus for your application before ordering, or call our tech line for guidance.
