Do you want chrome/bright zinc because you like the look or because the fittings are completely different?
Cause the bright zinc hose is for a later model typically around 73-74 the hose fitting at the steering box changed from a female flare to a male O ring.... And you can swap the fitting at the box to either design.... Also the bright zinc hose is for a federal pump & the dull chromate hose is for a Saginaw pump....
