99 Tacoma Toolbox Fit

I have a special bed lining in the back of my tacoma called "Perma Guard". Ive tried buying a toolbox to fit the altered dimensions of it, but with no luck, I couldnt find one. Is there any special made for this as I really do not want to remove the bed lining.


Any help is greatly appreciated!

A Picture Of The Bed

 

I had the same exact liner in my truck. What is so hard about the dimensions? There are TONS of toolboxes in all shapes and sizes.

I found one on craigslist that fit perfect. The previous owner of my truck had cut small holes for J-bolts to hook under the bed rails in order to bolt the box down.

 

The dimensions are 53x12 on the inside and 61 from outside to outside. The problem is that the actual flat clearance is very slim and its hard to find boxes that work.
