Hi,
If memory serves me right the Rad in the 410 sits on round anti vibration mounts with a plate and threaded mounting on each end, these often referred to as bobbin mounts and are available from a number of suppliers.
I can't remember who I got mine from but the company below do the same type
WDS Component Parts | Standard & Machine Components | WDS
Unfortunately neither the BOC or BODA seem to events listed on their websites, or if they do I could not find them so I will see what the lasts bulletins and newsletters have listed and get back to you unless someone beats me to it.
Geoff.
