Just a quick non-A body question

Okay, we'll eliminate the Fury then. On a sedan model, is there any way to tell, just by looking at the car, whether it's a Belvedere or a Savoy? The only badging on the outside of the particular car I am talking about says "Plymouth". Thanks again in advance.

EDIT: Why don't I post a few pics so you aren't in the dark here. And from what you said about the Savoy being the least-optioned of the three, I'm starting to lean toward that direction for this car. I looked closer at my pics, and it appears this car is a radio-delete option. That would point me toward it being a Savoy. Does that sound reasonable?
