The BoxRec stats says Barrera is one inch taller than Pacman. The HBO-stats where like this (and this looks more convincing when seeing in the fight and weigh-in that Pac was AT LEAST as tall as Barrera):
Barrera:
Height: 5'6"
Armlength: 24"1/2
Pac:
Height: 5'6" 1/2
Armlength: 25"
Don't know the reach but that also looked like Pac advantage. I'll look that up further...
