Depends on how fancy you want to get. You can buy headset wrenches in the specific size of you top lock nut, or you can get away with using a large crescent (adjustable) wrench. Some of the top races have wrench flats of a different size than the lock nut so you need a wrench to hold that as well (during assembly). But some top races have knurled edges instead of wrench flats, and those can be held with a big pair of channel locks.
