I believe this vehicle to be a poser. This is a restoration that was made to look like a Gran Sport. The fender badges are incorrect. They list it as a 401 Dual Quad. There is no such thing. The rear axle carrier does not have the circle with x, indicating a posi. The carrier assy looks to have a plug on the right hand side. It has the accessory switch which indicates rear defog, but the rear deck cover has no rear defog duct. Of course it has the optional horn bar steering wheel with no horn bars! The exhaust is all wrong. Finally, it is grossly overpriced.
