Part of the risk you take in buying a cartridge.
Ask for a close up photo of the cantilever and ask specifically if the cantilever is straight and not twisted.
That being said, unless the cantilever is making contact with part of the cartridge it shouldn't, it can still be mounted. I find the old Wally tractors easiest for this.
Another point - I find that Dynavectors are commonly off, and I am not surprised that a Dynavector is the culprit in this case.
