I found out about a Tbird Parts place that I had not heard of before. It is called Auto Krafters, in New Market, VA. Their website is: http://www.autokrafters.com/v4/go.gn...default&d=home
Their telephone number is 800-228-7346 FAX 540-740-8011.
They have an 84 page '58-'76 Tbird Catalog that you can download and view with Acrobat. It is chock full of parts for Tbirds, including tonneau covers for Squarebird, Bulletbird and Flairbird convertibles! Check it out!
