63 2-door Impala 327 3-speed. I need help duplicating what Chevy did originally for an over flow tube for the radiator. The filler neck has a 3/8 hose fitting where there was probably a tube attached and routed to point to the ground. I would assume there is a clip or two to hold things in place. Does anyone have a picture of what this is suppose to look like? Any help would be appreciated. Thanks.
