This is what you get!
I provided the above items for something like $2.50
Bottom side of laptop shelf.
I removed the conical grey bolt cover on the inboard front of passenger seat, the darker grey horizontal trim beneath the front of the passenger seat and the trim over the passenger's forward outboard seat mounting bolt trim. Both the conical cover and the trim on the other front seat bolt molding is removed by pulling straight up. The horizontal trim is removed with an allen wrench (Sorry, do not know the size). removing one screw on each end. I used a 15 MM socket to remove the inboard seat nut but, had to use a 15 MM box end ratchet wrench on the outboard one. Non power seats are probably entirely different.
I left the rear seat bolts untouched.
I used to stainless screws and lock nuts to mount the base to the metal strap which I bolted down under the seat mount. No holes were drilled through the floor board but, I wouldn't hesitate to so.
Next, I just played with different lengthes of pipe and number of angles to get a good compromise position. I recommend checking things like seat movement, climate controls, audio access and to make sure it is clear of an airbag deployment.
The "Quick Disconnect" is about 4 " up from base.
$43.00 bucks and 45 minutes later you have a laptop mount
I could have shaved five to ten minutes off of that if, my mentor hadn't insisted of pics.
Don't even mention the steering wheel cover
Mrs. F9 bought it for me and I have tried my best to "speed" up it's normal wear. and tear!
Each time I do a mod, I learn a little more. Of course I did not to think of taking every tool I might need to where I worked on the mod so I scrambled to find allen wrenches. Located a 30 piece 5 buck chinese tool kit or would have listed allen head size.
