Hi, Group, There is simply not carpet available that is like the dense pile used in the '59 Imperial. I know fellow member Richard Burgess finally bought some sort of household carpet for his '60 because it came closer than any to the style. About the best you can do is to install loop carpet, and almost no one will know the difference. I checked everywhere when I did my car and ending up saving and re-dyeing my original carpet. Good luck, Rex Crews '59 and '60 Crowns and '61 Custom
