Stainless roof inserts were offered between 1959 and 1963. They fit in the space in front of the crown on the roof. The stainless panel were a catch-up ploy to compete with the Cadillac. That marque had been offering a special model called the Eldorado Brougham which had a stainless steel roof. For the folks at Chrysler, giving the Imperial a stainless steel roof would have been a tooling nightmare especially since the recession of 1958 had hurt sales severely. The folks at Mopar used good old American ingenuity and crafted a stainless steel panel over the sheet metal roof held in place with the existing hardware for the crown and windshield trim. Voila! Instant stainless steel roofs. Bye for now. Doug 58 Crown coupe
