Made a little custom accessory that being a skateboard rack. used 1/8" x 1.5" wide flat stock steel then bent it with hammer and wood blocks. Glued some foam into the bends for extra grip on the skateboard while in place. Went to ACE and got longer hardware to go into the stock location of the luggage box. So the rack is fasten between the luggage box and rack. Been running all summer long with no issues so far. Need to figure out how to make a lock on it, can't leave it unlocked while running into the grocery store at the moment.
Need to make more custom mods for fun. ACE is the place if you need any specialty hardware.
