First of all, that "302" looks pretty awful. Were the numerals constructed out of the Stay-Puff Marshmallow Man's fingers? If re-creating it in vector form is necessary it looks like a pretty easy job. For a quick and dirty (and not faithful re-creation) of the numerals you could set the "302" in something like Eurostile Extended Bold (or Microgramma Bold) and then apply a corner filet function on the sharp corners of the lettering.
