The stem will be solid steel running into the trunk then
welded to a plate bent to match the contour of the front
of the trunk. A plate will be bent to fill the hole I
I cut in the trunk wrapping the seat. Then it will all be welded then reglassed to seal.
I'm thinking small braces leading to the struts for side to side support near the rear.
The trunk will be level and match the tank lines.

The rear mount will most likely be lockable and blend into
the new brackets for the tail lite I'm putting on.
