I've seen most every bike brand that i've sold have frame manufacturing boo boos. Bad welds/brazings, miss machined faces, missing braze ons/cable stops, cracks out of the box, miss aligned frames and forks, and more. Yet these issues are few and far between and the good companies take care of them when presented with the facts.

It seems that this is what happened. I would look at the replacement fork closely and have no qualms about using it. But i would keep the used fork for a while. Andy.
