vacuum for Lucas dizzy

Bill H and I have been having a side conversation about Webers and Mallory
distributors and he mentioned that David Anton prefers the Lucas dizzy for
it's advance curve.  So I'm going to dig out my old shot Lucas and see if I
can rebush it.  Any thoughts here?  And where does the vacuum line connect:
to the manifold or to the venturi in the carb?  Thanks.
