Here is the underside complete. Side struts are 2" X 2" X 3/16" angle and the center strut is 2" X 2" X 3/16" square tubing.
The rear connection of the center strut.
The underside of the towing A frame 2" ball accessory.
Here flipped over to show the top side.
There will be additional stiffening ribs installed when the crane work is done.
So moving along, hopefully we will get the Cavalier rear axle assembly and wheels installed tomorrow. We will see if we can take it out for a run to check tracking.
