damaged gears from UPS

[ILuvPizzaTimes10]

i would personally NEVER use used gears. unless for a track only run it to blow it on a budget rear end they will always make noise and wont last. reason being is i dont care how Good you are at setting up gears. you can never acheive the same attack angles unless they are put back into the same exact housing they came from. So the damage on those will just add to a not reliable rear end anyway. i say file a claim. But how do you know it was from shipping? do you have the chips that came off? the damage pictured can happen from inner pinion bearing failure as well.
