I have a "77 350 with a Rochester carb. I have a disconnected cable that needs to have the protective sleeve replaced but since I don't know what the part is i am in a quandry. the "part" is a cable that comes off of the drivers side of the carb then snakes underneath to a support bracket. the end of the cable has a chain on the end that looks like a brass "dog tag' chain and looks as if it should be attached to a vacuum that has the matching chain end on it. any help would be appreciated.
