73 vacuum advance can

Does anyone know the part number and where to get one ? It does not have to be an OE vette part but just work the same....

If you are talking about the control unit, they are available from any of the aftermarket suppliers.

I don't have my Lars spec sheet but ECH VC1765 comes to mind. Ask napa for the specs and wait for some others here to chime in before you buy. You want your vac can in 2" under your idle vacuum , so by 13".
