cadillac fleetwood question

I have a 55 cadillac fleetwood four door. I cannot figure out if it's a series 60 or series 62. anyone know a way to tell? thanks

 

the tag on the firewall should tell you what series it is.

 

It's a 60 Special, but usually called a Fleetwood. 60 series Cad was a 1 style (4 door sedan) only line for many years.

 

Series 62's are the bottom of the line. Fleetwoods are 60 specials.
