like an idiot i threw away the nozzle fitting along with the distributor vacuum advance when i replaced the diaphram. i'm astonished how hard this has been to replace. several trips to hardware & autoparts stores has yielded nothing: my thought was to replace it with a brass nipple fitting, but so far none are small enough. neither do i want to pay npd $12 + min shipping charge for a 'concours' correct part. is there a cheap & easy way to fix this that i've overlooked?
