Help / '69 Z/28 air cleaner opinion?

[roadster]

If car has fuel line support bracket from factory (stamp rite ) should be a later car , later cars at some point went to base with ridge not flat bottom . The flat bottom breathers sell for more money . Other ways to tell if hood was added , solenoid on firewall assembly line mounting and should have switch on accelerator pedal and special lever to mount switch under hood . If his base does not have thermactor ( round gizmo on top of snorkel it is for a manual trans and quite valuable ) . Pictured air cleaner is flat base .
