They do mount on the stock hood, I do remember that. Granted, I was like 8 when my dad sold it. When I get back to the states, I'll post pictures of his. He had like 3 different ones. He raced the Mickey Thompson circuit back in the late 80's and was number 56. He had a Paul Turner built motor and I'm pretty sure he had a Paul Turner exhaust, but not real sure. I don't want to ask him many questions, because this restore is a surprise for him. But the one that had the nose, was his outdoor play bike.
