939a2 serpentine belt part number clarification requested

[captain]

Parts sticky, google doc and misc posts list 2 different belt numbers for the 8.3L K080675 and K080680. I think last part of that is the length. What one is correct?

Thank you

I used 680 yesterday on a truck.

If that fit then that works for me. Thank you.
