3.0 GETTING STARTED / INSTALLATION
Back to Table to Contents
3.1 LEVELING AND SUPPORT
The vehicle should be on a level surface before you start. Leave the vehicle on the ground
and remove all body mount bolts and lower bushing halves. Some bolts may be rusty, you may
need to apply penetrating fluid to remove them.
3.2 RADIATOR SUPPORT
Once the bolts are out there
should be enough room to slip
the top mount in the frame. With
the top mount in place, install
the interlocking lower mount.
Coat the threads of two 1/2 X 3”
bolts with anti-seize and loosely
thread into the body.
3.3SIDE
LOCATIONS
When there is enough room,
remove the old mounts and
slip the upper mounts in place. Coat the threads of your 7/16 X 3” bolts with anti-seize and
loosely thread through the lower bushings and into the body with a flat washer and lock washer
as shown in the diagram on page
Repeat for remaining bushing locations on that side.
3.4REPEAT
Repeat steps on the other side of the car.
4.0 FINISHING
Back to Table to Contents
4.1 TORQUE
As rubber mounts tend to compress and distort over time and all floor pans are slightly different,
ensure that the hood and fenders line up properly with the body, and that all bushings fully
contact the floor before torquing. Use additional shims (not included) to adjust as necessary.
Cross measure the frame to ensure it is straight and square to the body. When the frame is
squared in, torque all bolts to 140 ft lbs.
NOTE: Recheck torque after approximately 100 miles of driving.
