I have a Sept.1969 Z/28, The radiator I believe is original to the car(yes, CB), with a build date of June. On the passenger side bracket that is attached to the radiator and secures to the radiator support is a clip that is molded(part of) this bracket on the side that seems it's only purpose it to secure the overflow hose. I called someone I know yesterday that also has a late 69Z and their CB radiator has the same. Did they have a change in design on this bracket. Did this radiator also recieve a seperate piece that attaches to radiator to hold the overflow hose to secure it in two different places? Thanks! Larry,69Rfine
