Just to put this into perspective there have been no "sudden and catastrophic" failures of the chassis lower wishbone mount.
Bar one, which was sudden but thankfully not catastrophic. Thanks to Rog G's alert, owners who follow this forum will hopefully have checked for signs of stress (although the failure of my front wishbone member was on the underside of the bushing tube and therefore difficult to view; the rear member failure was at the weld to the tube). The newer wishbone and mount do look like an improvement on the original.
