[Healeys] Question on pulley/belt configuration for air conditioning

[David Porter]

I agree with the others, however the problem is usually finding the 
right pulleys and water pump shaft length.. I've done 2 like your first 
picture and so far both have worked as advertised. I don't like running 
a V-belt on both sides, but so far so good..
