Need to replace belts on '13 GT

Looking for part numbers for both belts. The main belt is easy to find, but I can't seem to find the smaller belt anywhere. And from the looks of it, the smaller belt needs to be cut off in order to replace the main belt.
 
Ah! 12+ IS only the 1 belt. So many people kept saying it was the same as a '10. Ugg. Anyway, this was quite helpful.
