Over the weekend, I finished mounting my various recovery/emergency tools. On the 4x4 Forum, I posted the pics of FourTreks Hi-Lift mount and the "Paco Stealth Mounts" I fabricated for my shovel.
Hi-Lift & Shovel Mounts for Gobi Stealth
I also wanted a place to mount my fire extinguisher, recovery kit, and tools. The "shelf" above the driver's rear wheel-well seemed perfect. I didn't want to drill into the FJ body so I used the existing Shopping Bag clips (or whatever they're called). I purchased some 1/8" x 1 1/2" x 3 feet Aluminum bar. I cut the bar in half so I had two pieces measuring approximately 18". I purchased some longer screws with the same metric thread size as the stock screws. Finally I drilled of series of 1/4" holes in the bar for mounting various things.
Here's a pic of the setup:

You can the see the Super Quick Fist I mounted to the bar that's holding the extinguisher. I need to purchase a few velcro straps to hold the bag and tools in place so they won't conk my labs in the head when I take a turn too fast.
I also wanted to mount my Mag-Lite and thought about putting it along side the extinguisher. However, I really wanted it closer to me--within arm's reach. I realized that there's plenty of room below the rear bench. So I used a self-tapping #10 screw and mounted a regular Quick fist underneath the passenger side bench.
Here's the picture:
The rear seat still folds down without any problems. It doesn't even touch.
Overall, a very productive week end. I have to say, I love quick fists. They're so damn useful, I want to stick them all over my cars and house.
