In the bottom picture, you can clearly see the left side torsion bar. Also worth noting in the bottom picture is a heavy copper wire which is attached the the left side idler arm. The wire is installed to prevent the wheels from turning from side to side. ( I also have a heavy bar which is bolted to the frame, in case I wish to tow the cradle up to the car wash to rinse it off ) With the engine still in place, the tongue weight is quite heavy, but a truck will handle the Cortez cradle "trailer" rather nicely.
