Shelby Short Throw Shifter Installation - How To Install A Shelby Shifter

To the left are the tools and to the right is the Precision Short-Throw Shifter kit for the Mustang GT's 5-speed. Remove the shifter and parts from the packaging and assemble the components to the base. Install the rear mount bushings and mount plate.

Apply Loctite to the Allen-head bolts and attach the blue shifter arm.

Torque the shifter arm bolts to 18 foot-pounds. Install the support arm polyurethane bushings.

Once the Shelby shifter is assembled, get into the car and slide the factory shifter to neutral. Unscrew the stock shifter knob and pull off the shifter boot and bezel.

Reach into the console and pull the rubber boot straight up. Now you'll need to get under the car, so apply the emergency brake, put the transmission in gear, and elevate the car on a lift (or jackstands).

Use a permanent marker to mark the position of the bolts on the driveshaft support brace (where the two shafts meet) and on the transmission mount flange.

S197 Mustang driveshafts are two-piece. Therefore, removal requires pulling two 13mm bolts in the support brace where the two shafts meet. The reason for marking this brace is so you can return it to the factory location. You also must remove the four 12mm bolts to pull the driveshaft from the transmission output shaft balancer. You'll need another person in the car to shift the transmission in and out of gear to rotate the driveshaft so you can access the bolts. Be sure to take note of the spacer locations.

Loosen two of the four transmission yoke-to-driveshaft bolts. Release the emergency brake and put the transmission in neutral in order to rotate the driveshaft to expose the other two bolts that secure the transmission yoke to the driveshaft. Be sure to put the transmission back into gear and apply the emergency brake to remove the bolts. Otherwise, the driveshaft will turn.

Loosen the two bolts (one per side) holding the center of the two-piece driveshaft in place.
