Bed Width

I need the bed width...inside the rails, and below the rails too.

I am putting some subs in my bed, and my truck is an hour n a half away, so I need the measurements.

How about this....SINGLE CAB SHORT BED....
Inside the rails.....
Below the rail width.....
From front wall to tub depth.....
From bottom of rail to floor height.....




This would help me TREMENDOUSLY!!!

no one?

Someone, get out there with a tape measure, please?
lol.
