Hi Gordon
On a standard car the spring is bowed and suspension movement causes the spring to lengthen compressing any rubber chocks and holding the axle in place.
On a dropped axle car the spring is flat or has a negative bow and suspension movement causes the spring to shorten….any rubber chocks would be useless.
Robert..
The three large bolts on the plate fit the axle shackle eye, unused radius arm hole and the dropped radius arm holding all three to the axle with no movement before or after fitting. The bolt holding the spring is, I'm sure, a shackle pin with shoulders and grease track allowing the spring to rotate. On my installation the grease nipple at the end of the pin faces forward as shown below. (On my axle I’ve installed double dampers with the ends fitted to a damper pin drilled and tapped into the bolt where the radius arm was).

Hope this helps but I’m sure Steve or Terry can comment further.
