I recemmend Stock Interiors. They have a great selection and I found them to be the best priced supplier. I recently purchased new carpet and matching floor mats for my '62 which I'm hoping to install this weekend. Their website is easy to use and full of useful information. I also purchased the original type 12-piece 'Body Sound Deadener Kit' from Fusick.
