One last bit that had to be soldered into place... is the part where the bungee wraps around under the axle on each side. Based on looking at photos in the Datafile with a magnifying glass.... I believe that it is actually the rear spreader bar, which is supposed to bend around underneath the struts on each side. However, isntead of trying to bend the rear spreader bar and struggle with aligning it, I chose to isntall the bungee wrap posts as separte pieces of brass tube.
FInally, everything is cut apart! which might seem counter-productive.
