Its a unibody. You can pretty much cut the front rails at the firewall or cut them out at the torsion bar mounts. The front clip has value, ie fenders and radiator support as well as lower valance, bumper, supports and suspension. I would take the inner fenderwells off your hands if your selling them but they need to be cut out at the spot welds to be reused. Doors are useable, glass, interior, etc. Rear might include fuel tank, rear quarters if they are cut out past the usual mounting lines, rear bumper, mounts and all the trim pieces. There is a wrecking guy down in San Diego that is selling a front clip for a 65, look on craigslist San Diego for Barracuda. He has had it for sale for at least 2 years. I almost bought the front clip minus fenders for 150 but couldnt pull the trigger and his prices have not come down in 2 years. You can do it with a sawz-all and a box of blades. Nothing is over 14g as far as I can tell. Even the frame rails are suprisingly thin.
