Chris cut the end off the trailer hitch arm where it mounts to the trailer and then used the end he cut off as a template to create a longer extension piece to be welded onto the arm. Sorry the pictures are not great. I had removed the arm from the trailer to paint it. My nephew is up north with his family. When he gets back I will update the post with a picture with his trailer attached to his bike. I talked to my sister earlier and told her it's all set. She told her son and I could hear him scream WOOHOO!!!!
