Jon, it is hard to tell from the pictures, but I am thinking the roll cage and subframe we can see bolted to the floor are owner additions rather than part of the original Speedex frame structure. Not sure that roll cage would do much and it would probably not comply with any current regulations, you are also not going to be racing it, so perhaps remove the whole thing and then rethink the floor and seat back area.
