Parts Included: License Plate mounting bracket Assembly. Includes Base Plate and
License Plate Holder
License Plate Mounting Screws: (4) 6mm X 12mm (Phillips head) and
6mm (10mm wrench size)
Base plate mounting screws: (1) 4.2mm X 35mm, (1) 9/16” nylon spacer,
(1) Fender washer, (1) 6mm X 35mm bolt with (1) washer and (1) washer
nut
Tools Needed: 7mm, 8mm & 10mm sockets with ratchet Note: 1/4-inch drive preferred
but 3/8 will work but extra caution will be needed when tightening
screws
Phillips Screwdriver
10mm wrench
1/4-inch drill bit and drill
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: Remove the center factory screw using the 8mm socket as shown in figure 1.
Step 4: Carefully drill a ¼” hole for the front bolt. The drill bit will be up against the plastic
centered in the semi-circle cut out as shown in figure 2. Drill straight up.
Step 5: Start the rear screw where you had previously removed the factory screw using the
4.2mm X 35mm screw, spacer and fender washer. Note: The screw will be placed through the
base plate, then the spacer on top of the base plate and then the fender washer to allow the
spacer to sit flat. Do not tighten. Now start the front bolt by sliding the washer nut over the
hole just drilled ensuring the washer nut is under the J-Clip as shown in figures 3 & 3a. Slide the
bolt though the base plate and into the hole previously drilled. Tighten both fasteners.

Step 6: Secure the license plate and frame (optional) to the license plate bracket using the
screws provided. Requires the Phillips screwdriver and 10mm wrench (Not included).
Step 7: 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 grab frame at arrows (See figure 5) and rotate. If the plate is high on left or right
side, rotate high side down slightly and release. Repeat as necessary. Once leveled plate will
remain level.
