Using bed bolts to tie down organizer

I'm planning to use the front and middle bolts of my 2009 Taco (double cab long bed) to tie down an organizer (Brand Silver Shield). I had it made for my Tundra, now I adjusted the width to fit in my Taco. (see pic attached from Tundra)
The organizer has a 1/2" plywood at bottom, and since it sits on top of the bed, there is another 1/2" gap between the bolt and top of bed, so I think I would need at least 1" leverage on the bolt to work it out.
My question is if the 2 middle bolts are enough to hold the organizer in place. The 2 front bolts are offset 2" outside of the area where the organizer will sit, so maybe I could tie it to those front bolts with a metal strap (I'm not sure if this will work). Another problem would be the room I need to have in order to tighten the bolt.

 

I don't think you have that much length with those bolts, but I am not 100% sure. We've only had one box off a Tacoma, but based on how everyone else's trucks are put together all they ever give you is a little over 1". You could just change them out for ones long enough from a bolt place. Strapping the fronts should do the trick- it's the rears that are going to do the bigger job anyways (unless you wheel hard and/or jump your truck on a regular basis!)

 

Thank you guys, I will try it and let you know.

 

Yep , bed bolts are pretty long , I removed mine and added some anti-seize and reinstalled them

 

What are the size and length of the bolts?

 

Yikes!
I'd guess 14mm x 2.0 thread pitch, length...
Can you pull one and take it for reference? That is the best thing to do...
