Adding a prefab to gameObject at a certain position in runtime

Hello all,

I'm building a 2D snake game, consists of three images: head, tail, body

I'd like to add a the "body" prefab of the snake body once it ate a food. I need to place the "body" between the head and the tail each time as it increments. see pic:

I see t$$anonymous$$s as a list of body parts that increments as the snake eat. List of x prefabs with n items, such as: x=1: snake head, x=n (the last position) is the tail. and in between is the "body". The "body" should be added always at the position of n-1, right before the tail.

t$$anonymous$$s is the code I have so far... and it will add the body part but on top of the current body.

     public void AddBodyPart()
     {
 
         GameObject _belly = Resources.Load<GameObject>("SnakeTileStraightSwallow") as GameObject;
        Transform part = (Instantiate(_belly, snakeBodyPart[snakeBodyPart.Count-1].position, snakeBodyPart[snakeBodyPart.Count - 1].rotation) as GameObject).transform;
         if (!snakeBodyPart.Contains(part))
         {
             part.transform.SetParent(gameObject.transform, false);
             snakeBodyPart.Add(part);
         }       
     }
