Unsafe,

I like your idea of a pivot. I would still like to see a closer shot or a sketch. I am contemplating a conversion from closed to open, but don't have the time to research it now. I am busy working on getting my 54 back on the road. Of course that could all change if I were to come across a 55 diff.

Keep up the inovative work. I like it.

Take a look at this from TCI, it may give you some ideas about the pivot.
