The original 47-54 wheel is forward of center in the wheel opening of the fender.
Is the wheel centered in the center of the wheel opening of the fender on original 55.1 trucks?

No, it sits forward in the same position as the earlier ones. The difference in the mounting hole locations is due to the hinged mounts attach forward of the axle and the '55.1 mounts are under the axle.
