Being new to Z' and just two weeks in to a full restro .I would like to know what colour suspension and running gear should be ? I.e suspension arms ,propshaft,springs ,shocks etc etc
Basically what wasn't Black .some items look like they might have been grey?

I think your find it was all black apart from the engine block, pulley, and a few engine brackets not sure about the fuel tank though although I am positive about the moustache bar being black
