Legendary Mods for trade

I have two Legendary Gunzerker Class Mods, Level 62 & 72 and a level 50 Legendary Siren Class Mod. Will trade all three for one level 72 or OP1 Legendary Soldier Class Mod. Been farming LLMs and tubbies non-stop to no avail.

EDIT: Will also throw in level 59 Legendary Soldier Class Mod for trade. Looking to upgrade.
