I started doing a '68 Fairlane fastback several years ago, ended up selling it. I joined the Fairlane Club of America, seems to me they had links to some suppliers. I do remember buying parts from Dearborn Classics http://www.dearbornclassics.com/
Many moons ago I picked up a '68 vert while stationed in Brunswick, Maine. One night while cruisin around I pushed the headlight dimmer switch right through the floor pan! Now that's rust, lol :)
