Bed measurements

I was wondering if anybody here could give me the inside measurements for their truck bed for their 2.5 generation? I'm trying to figure out the difference between 2.5 generation and a second generation. The top bed rails is what I'm looking for. I'm trying to figure out fitment of a bed cover.

Thanks

need to know more, what year are you trying to fit and what is the truck configuration? There were different bed sizes.

Above is thread about the DC with pics, measurements.

 

and this might cover the others https://www.tundras.com/threads/2-5-gen-bed-on-2nd-gen.109898/

 

I'm sorry but I'm looking for the top rail measurements for fitment of a bed liner. Not trying to put a different bed on my second generation.

 

right but there were different bed sizes depending on configuration.

Short bed, long bed and then the 6.5 foot bed. which configuration do you need measurements on?

 

6.5, I'm sorry I didn't mention that,

 

First link I posted has measurements for the 6.5 bed, 2.5 gen
