Looking directly square on at the front, does the wheel evenly split the distance between fork blades? If you, that is another positive suggesting no fork damage. If the wheel does not evenly split the distance, the problem could be either a bent fork or an out of true wheel (just turn the wheel around and install to see if the even split thing changes - if not, the wheel is probably OK...
Nice bike. Too bad the dork disc is bent.
