The roof of the 120B is a permanent soft top. We are considering doing something special with that. Here are a couple pictures of the opening currently.
Little bit of hard wood and some chicken wire. Gotta love classic construction!
This is what we are currently thinking. A sliding rag top! When closed it will look very similar to the permanent soft top while adding the ability to open it up for cruising!
