I really need to replace all of the vacuum hoses on my '72 and after searching the web I can't find all of the hoses (not even MSA). Has anyone used the generic Silicone hose kits or injector/fuel line hoses? I know I won't get the pretty bends, but I'm thinking as long as I keep the arc wide enough I should be fine. Any suggestion on what sizes (I.D.) I'll need? Thanks. - Dave
