if you want to get top dollar for it you will need to be aggressive with your presentation. Tucked in the corner of a shed , covered up with stuff, doesn't tell much.. how about like this, I have for your inspection a 66 FB in excellent condition, all minor rust issues have been professionally repaired. the title is in hand and the vin numbers stamped on the body match the title, it is equipped with a factory 9" rear with trac-loc , which I believe to be original to the vehicle, the interior is complete but needs restoring..All the original parts are present in outstanding restorable condition. The vehicle is a rolling chassis and all parts are labled and boxed, the tinted glass is all present in excellent shape as is the chrome trim pieces. Don't let this classic mustang project pass you by.. Now as to the value when you take a bunch of pics of everything, and show that it really is a great vehicle to buy you might get 5+ or more from the right person, or a lot less, it all depends on what is there and the condition, if it doesn't need quarters or any sheetmetal work, has good doors, fenders etc it will be worth more, the lack of an engine is the easiest part to overcome, if the original shifter for the trans ia avail that is another plus. If it was together, not restored, but together you might get more. At the present time the economy is a bit flat, but look what a new mustang body costs. FB's are hot and you might think about the least you will take for it, put it on a sale site like ebay with that price as a reserve, and let the bidders decide, Heck at BJ this weekend they sold a 1963 VW bus for 198K anything is possible!
