interesting joolz, please tell me more, especialy in regards to the leaf sprung rear end! (EL wagon)

not sure what the struts/rods are called but its the upper rod on the outer of the diff just inside the wheels.
with leaf springs a 3-4mm plate slightly wider than the U bolts can be fitted between the diff and the springs (rear of diff)
the plate should be drilled so the U bolts go through it so it cant fall out or move around.
