PROCEDURE:
1. REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ
INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION.
2. Starting at the driver side-front of the vehicle, remove the tape covering the factory oval holes
in the inner body panel located by the front tire. Partially thread a Plastic Retainer onto the
threaded end of a Bolt and Nut Plate, (Fig 1A). Once you have assembled the Bolt and Nut
Plate, insert it into the factory oval hole. Hold the Bolt end with one hand and tighten the
Plastic Retainer with your other hand. NOTE: Tighten the Plastic Retainer until it is flush
against the side panel, (Figure 2). IMPORTANT: The Plastic Retainer is designed to prevent
the Bolt Plate from falling into the body cavity and to aid in mounting the Bracket.
3. Next, select (1) 12mm Bolt Plate and partially thread a Plastic Retainer onto it. Insert the Bolt
Plate into the forward, smaller oval hole and install as per Step 2, (Fig 1B & 2).

Bolt Plates. Secure it with (2) 12mm Flat Washers, (2) 12mm Lock Washers and (2) 12mm
