Is 6.5' bed length a 77.6" or 78.7"?

Hi all,
As of yesterday, I am the lucky owner of a 2024 Tundra Limited DoubleCab with a ... "standard bed" (or 6'5") who's looking for a hard Tonneau cover. And that's where my confusion starts.
The vehicle's tech specs lists the bed as 77.6" long (which I confirmed by measurement).
However, most manufacturers list their covers as fitting a 78.7" bed (interior measurement).
Searching this forum didn't really yield any useful comments on this.
Has Toyota just changed/shrunk their Tundra's standard bed length with ~1"? Are there multiple 6.5' types of beds for Tundras? Or am I just missing something obvious?
Thank you in advance for any answers.

 

ryanwgregg thank you, my model is 8352. Then I guess I am out of luck finding a manufacturer which offers covers for 77.6" beds

 

When you find one, it should specify whether it fits, and a quick phone call should confirm either way.

 

So I ended up buying this one and it fits. I guess the confusion came from the various vendors as they advertise different dimensions (77.6, 6.5 or 78.7), even though it is for the same type of truck. If you have a 8352 model, I would advise you to go with those vendors who advertise 6'6" (or 6.5') or 78" (78.7")
I hope this will help someone in the future.
