I agree, it's probably no more than a commando car. It's kinda rare not to have an 8 3/4 with a commando and a 4 speed. I've only seen one documented car that came that way in '66. It's a little hard to tell but the rear springs don't look like 6 leafers either but it could be just the angle. I noticed that it didn't have a good front suspension shot to verify a sway bar. Even if it originally had all the correct FS parts, there is no way to verify it's real unless you have the fender tag, build sheet or a copy of the IBM card from Chrysler Historical.
