Now why didn't I think of that. DUH! Here are some pics. The first pic is with the floor panel setting in place (close but not exact).
Studying it closer I guess the original floorboard was removeable and I could probably do that with this one but probably be better to weld it in and fabricate collars for the body bolts.
