Hurst Competition/Plus Installation Kit - GM. The Muncie (452, 453) transmissions can be identified by the fact they use a bolt to secure the shift arm to the shift fork on the transmission. 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.
