Assembly Instructions:

1. This kit requires the removal of the factory subwoofer. It also requires gutting and trimming the inside of the center console. The instructions will not cover either of these steps.
2. Thread the transmission adapter onto the shift tower until the shift tower starts to poke through the nut. The adapter can be locked in place with the OE jamb nut but is not necessary.
3. Assemble the shifter using one jamb nut and one heim joint. The jamb nut and heim joint should be threaded all the way onto the shifter. Tighten the jamb nut onto the heim joint to lock it in place.
4. Assemble the shifter and 90° floor bracket. Use the long 1/2" bolt, two heim joint spacers (one on each side of the heim joint) and two washers. The slotted screw holes should be located under the heim joint with the bracket installed.
5. Using the two short 1/2" bolts and the washers, install the linkage with the short leg of the bend on the transmission side. The linkage should be installed on the drivers side of the shifter and transmission adapter. Blue thread locking compound on the nuts is recommended but wait until final assembly to apply.
6. Locate the shifter and 90° bracket position. The stud on the top of the shifter should be 31-1/4" from door panel above the window switch and below the heated seat switch on the drivers side. Make sure the shifter and bracket are perpendicular when this measurement is taken. To verify this measurement it should be 35-3/8" from the stud on the shifter to the same spot on the passenger side door panel. This step is easier to do with extra help.
7. Once you are certain on the location of the floor bracket. Mark and cut the carpet for the 90° floor bracket.
8. Double check the measurements in step 6 above. Then install the self tapping screws in the middle of the slots. You will screw through two layers of floor.
9. Check for shifter clearance. You may need to adjust the floor bracket left to right. If the bracket cannot be cheated enough using the slots then washers can be used on the 1/2" bolt to space the heim joint towards the passenger side. This will help avoid unnecessary holes in the floor.
10. If any clearance issues persist and the interference cannot be trimmed to clear then the linkage angle can be adjusted or the linkage can be spaced. Spacing the linkage towards the drivers side with washers will move the shifter to the passenger side. Bending the linkage for a tighter angle will move the pattern towards the passenger side and slightly forward. Straightening the linkage will move the pattern closer to the drivers side of the console and slightly back.
11. Install the shifter boot by trimming the tray. Any type of ~1/8" thick plastic (not included) can be used to sandwich the shifter boot to the plastic on the inside of the cup holder. The layers go, plastic cup holder, shift boot, plastic. Fasten with short self tapping screws of a large diameter from the inside out. Now cut or grind the excess length of the screws sticking out where the cup holder tray slides into the console.
12. The top of the shift boot can be tucked into itself for a better finished look. A few threads may need to be pulled depending where you want the boot to sit. Electrical tape can be used on the inside of the shifter to prevent the boot from sliding down too far. Or if you prefer the boot can be taped to the shifter on the underside after folding the top in.
