Tower clamp behind the cab
For the tower clamps, weld clip with weld nuts onto the frame. Center about the hole and slots under the weld plate just ground off, maintaining the same angle of rotation about the center.Note: For the tower clamp behind the cab, welding on the left and right sides may be easier.
Install grommet and route hoses through, aligning the tape or marks on the hose to the clip.Note: For the rear tower clamp, to bolt the clips together the following procedure may be necessary. Torque all bolts to 55 Nm (40.6 lb ft)

Place a tie strap through the top hole and then compress the clips together.
Install one washer and 8T-4186 Bolt into bottom hole.This longer bolt helps start the threads and bring the clips together.
Illustration 12 g06251258
Install washer and 8T-4136 Bolt or 8T-4195 Bolt into the top hole. This shorter bolt is needed in the top hole because the angled rear tower sheet causes interference when trying to start the longer bolt.
Ensure that all harnesses are strapped and properly oriented before clamping:
