Will an 8' box from a 2008 regular cab fit on my 2007 double cab?

Hello! Just bought my first Tundra a few weeks ago. A deal I couldn't pass up. Low mileage but some cosmetic issues.

My box has some nasty dents from a previous owner accident and the body shop wants the earth to repair it. I found a nice looking used box online and I am trying to determine if it will fit. This person is a considerable distance away from me so I cant just go look at it.

My Truck 2007 is a double cab with 8' box
His bed came off a 2008 single cab with 8' box

My cab to axle is 60" and I am having him check that measurement. Any other critical measurements I should ask for or general advice?

 

it's the same bed

 

This is great news, thanks for the quick reply. So there should be zero difference?

 

Where are you located? What shape is the bed of your box? There's a few people here with rusty beds that could possibly use your bed for parts to repair theirs. I would take a good look at the underside of the box to see if it's rusted. Take a look at the posts with pictures of the rust and then look to see if rust has started at those points from the bottom.
