On My 1961 MC-2 Bus the outside theme will be about Indian Motorcycles. I will be towing my Indian bike in my 13 foot v nosed cargo trailer. For starters I made 2 Indian logos the will be for the mud flaps at the back of the bus. They are made of stainless steel pipe with reflective tape. The will shine nicely in the day time and really shine at night. I will post more pictures of the Indian Motorcyle theme when it happens.
