I have had a few questions about my 12/67 Dearborn GT Fastback and a recently acquired salesman price sheet dated 9/22/67 helped solve them. i.e. Clear Windows with A/C. The prices listed match my window sticker (original) perfectly. I've seen a few threads that might be resolved by the information below.
Visibility Group - (including Left hand Remote Control Mirror, Under-hood Light, Luggage Compartment Lights, Glove Box Light, and Glove Box Lock; Hardtop Models also incl. Under-dash Courtesy Light) $24.01
Remote Control Left Hand Mirror $9.58 a separate option from the VG
Air Conditioner - SelectAire (Tinted Glass recommended) $360.30
It also lists the Unicorn 390HP 427 for $622.97
I'll work on posting a PDF copy.
