Starting to fill in the hole, first I repaired the bits it sits on on the right hand side. This part took a while to make, it's three pieces welded together to get the curved step at the front. The recess where the support for the front connects was done with a hammer and dolly. Next will be the similar part on the other side around the battery box.
The piece on angle is temporary, there to hold it all straight while it is unsupported.
