If you're installing new seat covers, chances are you could use some 1968-1976 Molded Seat Foam Back and Bottom, single seat. Not only will this padding provide better cushion for your driving comfort, but it will also extend the life of your newly installed seat covers!
Think about it...why purchase new covers if your padding is worn and misshapen? Your restoration simply isn't complete if you don't begin with a solid foundation for proper fit and great looks.
Injection molded foam cushions are pre-formed and ready to install.
