Is a '61 Dodge Dart Phoenix considered an A body?

Been a member on the FBBO site for a number of years and recently completed a '66 426 hemi build and looking for a new project. This car pops up and I'm looking to go see it next weekend, a 1961 Dodge Dart Phoenix with a 383 and dual cross ram and manual (assuming 3 on the tree from research thus far). Claims to be 1 of 12 with this motor/trans. Anyone know anything about these cars or where to get information before I make the drive?
