Toyota left the mounting point on the truck for stability in the new front pillar. Unfortunately, there is not a nut welded onto the back like on the top mount. The bottom mount just has a hole that accepts the plastic retainer on the factory Garnish, Front Pillar (LH) without the Grab Handle. Therfore, the following steps are necessary to create a solid mounting point for the New V2 Driver Side Grip Handle. Use the Rivnut Gun that is provided in the kit to compress the Jack nut on the lower mounting bracket. With the new Jack nut in place, you now have two mounting locations for the new grab handle.
Install your New Garnish, Front Left Pillar. Installing this incorrectly can result into the Pillar not seating correctly against the frame of your vehicle. If you do not feel comfortable with any part of this installation, professional installation is recommended. However, just as you removed the factory pillar, you'll slide the new one back into place. Starting from the bottom, pay attention to the two opening for the bottom of the pillar tabs. It is very easy to have the A-pillar miss them and then everything will be missaligned. Slide the tip of the A-pillar closest to the windshield and start working your way up the windshield. The panel should pop back into place just as easy as it was removing the factory trim piece.
After proper installation takes place with the New Garnish, it is time to install the New Grab Handle using the new bolt and screw (10mm shorter bolt on top/smaller phillip screw on bottom) included in your hardware package with the 2 bolt sleeves. The bottom will screw into the jack nut you installed. Whereas, the top will screw into the factory threads. If you have any challenge finding the threads with the handle on the pillar, remove it off the pillar enough to just see where the screws need to be placed. Start threading the bottom first, then the top. That should solve your problem. At the end, make sure the weather stripping on the side of the Garnish, Front Pillar is on the outside.
Insert the Hole Cover (included with package) on the top to hide the hardware you just installed. Repeat for the bottom hole location in the Grip Handle. Make sure that all tabs on the back side go into their respectful places for proper installation.
Enjoy your New V2 Driver Side Grab Handle!
