I also just found this, on eBay of all places which seems strange. Instructions for Ford Mustang Headliner Installation not a complete guide with pictures but helpful nonetheless. [url]http://reviews.ebay.com/65-66-67-68-69-70-Ford-Mustang-Headliner-Installation_W0QQugidZ10000000002149791[/url]

Have you tried Fordmanuals.com? They have ones on there you can download to your computer (for a fee).
