Need info on a tool box

I have a 2010 Tacoma sport with a short bed. every tool box that I've found is 60 inches for a small truck. well that's way to narrow for my truck. I would like for it to go from side to side which is about 65 inches. I want to put bed rails from the rear to look like their going into the tool box but I cant because of the narrow box. should I try a tundra box? or t-100?

 

here's pictures of the previous tool boxes. please help!

 

If you check out my build thread, Ive got a box that goes further onto the rails

 

Look at UWS. they make some at 63 for our trucks.

 

would a tundra, t-100, or a t-150 fit? its easier to find their tool boxes because I don't want to spend close to $400 on a tool box

 

I got mine from Lowes for like $150

Tractor Supply . They measured the bed then ordered it for me.
