It's a 7 litre no doubt about that really without knowing numbers and that stuff but also a Galaxie 500.

I'll have to email Tom, the guy who does the '66 registry and ask him about the interior packages. It might be that the 500 in the 7 litre version is a bucket seat car and the non 7 litre isn't. Although there is a '67 7 litre that is bench seat so I just don't know i'm so confused.

Where's that Richard, he probably knows also.
This one I know is all original and has bucket seats and is a Galaxie 500. Don't know about the seats but the 7 litre deal is just that, a special edition engine package deal. Which they might be the exception for the bucket seats. Although a person could order one without I'm sure just it was standard for the 7 litres.
