I would avoid taking parts off a bike that may appear abandoned; it might actually belong to someone who will seek it out as the fall semester begins. Most of the comments here are right, why do you need full suspension for a campus beater? Find yourself an old Schwinn Varsity or Raleigh Grand Prix (or something of the sort) from a yard sale put $50 into and you'll have a perfect campus bike. Remember your campus cruiser is designed to get you to class, and also not get stolen. Don't ride anything flashy!
