Base plate mounting screws: (2) 6mm X 22mm washer bolts with (2)

Step 1: Ensure all parts listed above are accounted for. Note: If at any time during the
installation process you need assistance please call [phone].
Step 2: Separate the license plate holder from the base by simply pulling the pull pin ring
outward and sliding apart.
Step 3: Base plate will be centered as shown in figure 1.
Step 4: Align the base plate with the front edge of the underbody panel as shown in figure 2.
Slide the front plate into the base plate to verify alignment. Base plate will be properly position
when centered on the bumper and the back of the front plate sits ¼” from the end of the
spoiler/bumper as shown in figure 2a. Note: Foam tape will help hold base plate in place while
fitting.
Step 5: Once the base plate is properly aligned remove the front plate and carefully drill a ¼”
hole for the rear mounting bolt. See figure3.
Step 6: Using the 6mm X 19mm bolt and washer nut secure the rear of base plate to the vehicle
by sliding bolt through base place and into the ¼” hole. Reaching inside, place nut onto bolt and
secure. Slide front plate back into base and verify alignment. After verifying alignment, drill
front ¼” hole and secure with remaining 6mm X 19mm bolt and washer nut.

Step 7: Secure the license plate and frame (optional) to the license plate bracket using the two
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. In some instances, 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.
