When you recently fitted rubber between the axle and springs of this car I believe you also changed the back springs. Would you please let me know if that is the case. If so, we should be interested to know, firstly, why that was necessary, and secondly, whether the poundage of the back springs fitted was any different from those which you removed, or whether there were any different characteristics about the springs Cx.{Major Len W.
