Step 1: Ensure all parts listed above are accounted for. Note: If at any time during the

Step 2: Separate the license plate holder from the base by simply pulling the pull pin ring
outward and sliding apart.
Step 3: Remove center spoiler screw (4.2mm) using a 7mm socket as shown in figure 1.
Step 4: Now position the base mount with the small hole towards the front of the car, centered
over the hole where the 4.2mm screw was just removed. Note: Tubes will be facing down.
Using the (1) 4.2mm X 50mm screw, 4mm washer and the (1) 9/16” nylon spacer secure the
base plate in place. See figure 2
Step 5: Once the base plate is secured using the front mounting hole, slide the front bracket
into the tubes to verify alignment. Remove when alignment is complete and carefully drill pilot
hole for the rear mounting screw. See figure3.
Step 6: Using the 6.3X20mm screw secure the rear of base plate to the vehicle using the
following method. Caution: When tightening the screw extreme care should be taken not to
over tighten screw or the hole may become stripped and lose its ability to secure the base

plate. Place the screw into the 10mm socket and begin to tighten. Once the screw is flush with
the plate stop. Now Tighten screw one half turn and stop.
Step 7: Secure the license plate and frame (optional) to the license plate bracket using the
screws and nuts provided. Requires the Phillips screwdriver and 10mm wrench (Not included).
Step 8: Slide the license plate rods into the two tubes located on the base plate. Slide the rods
into the tubes until the rods hit the pull pin. Simply pull the ring on the pull pin and advance the
rods. Release ring and continue to advance rods until the pull pin locks into place. Note: The
rods and spring-loaded pull pin are required to be sprayed periodically with WD-40 or any
other silicone type spray lube. Failure to do so could result in either the failure of the pull pin
or the rods becoming difficult to remove or reinsert. Note: In harsh environments, such as
areas where roads are either salted or sanded in the winter, spraying of the rods and pull pin
should be performed on a regular basis. Failure to provide this maintenance may void your
warranty. See figure 4. On some occasions the license plate may require a little adjustment to
level. Simply pull pin and slide plate out approximately two inches, grab frame at arrows (See
figure 5) and rotate. If plate is high on left or right side, rotate high side down slightly and
release. Verify alignment and repeat as necessary. Once leveled plate will remain level.
