Hi Mal,

I was staggering today through one of the US outlets of China, Inc, (otherwise 
known as WalMart) when I saw pretty substantial-looking moulded plastic pairs 
of car inspection ramps;  you know, of the sort up onto which one drives the 
front two wheels just prior to getting a faceful of old engine oil.

That'd give insulation, and a bit more distance to reduce chassis to ground 
capacitance.

        Cheers,

               Steve
