Transmission cases made in 1994 and 1995 have neutral safety switch mounting holes but do not have the top mount shifter bracket holes. Sonnax shift cable mount bracket 34913-01 allows installation of '94–95 transmissions or cases into '96–'97 vehicle that originally had case mounted shifter brackets. Additionally, if a late case has damaged or broken top mount bosses, the Sonnax bracket can be used as an alternative to correctly mount the shifter cable and allow reuse of the case.
