A quick internet serch would probably clear this up but I figured it would be some food for thought and I wanted to know what the "experts" have to say.

I know that Imperials first VIN digit are known as Y only because "I" would be confused as a number 1

but this has led to confusion as to whether they are C bodies or Y bodies ( they are C's)

From what I heard it is a simple lettering system starting with A and moving along. Being as concept and unused designs don't get used, it is a platform designation, thus the different body styles on the different platform (which is how the new 300 and the new charger Sedan can have the same designation LX). Why there was a big jump between the  Y body and the JX, but here is a single letter listing.

Imperials are condidered D bodies, they do not share the platform of the C bodies (which does not mean there can't be parts that interchange, there is a difference).

The gray area still remains with the Imperial.  It's like it's a forgotten step child.  I call them a C+, which is barely a passing grade.  LOL

Yeah, but the Imperial is not a Chrysler, it is an Imperial under ChryCo (at that day and age), even though people like to call it a Chrysler Imperial, but not like a Dodge Charger, Charger is a model name, Imperial was a brand (back when it was initially made), and not to be mistaken for the K car era Chrysler Imperial.....
 
If that makes any sense.

The idea that Imp was a separate brand from Chrysler was mainly a
marketing ploy after '66,  in reality, the '67-on unibody Imps
were essentially just extended Chrysler platforms, I think the actual
platform floor pan/trunk stampings were the same, not sure about front
subframe, but that was easily modified, Imp was not a clean sheet of
paper different car, it was just a slightly modified Chrysler, a C+ as
Steve says, and I don't think Ma actually ever used a D
designation.  My 69 Imp sure looked the same underneath as my 72
Chrysler.

I am trying to remember serial number designations from my old days working for the Chrysler Sales  Planning and Distribution Dept.  in the mid 1970's.   The poster stating the Imperials 1st letter was Y is correct.  The other C bodies at that time were C for Chrysler, D for Dodge and P for Plymouth.   The 2nd letter denoted model, such as  L for lowline (like Newport or Polara or Monaco depending on year) M for mid line like Newport Custom or Royal Monaco, H for highline like New Yorker, Royal Monacco Brougham or Gran Fury.   Then there was P for premium like Chrysler St. Regis, Dodge Diplomat (mid 70's C body).

Vin numbers, by and large, are different than the A, B, C, (D), E, F, etc., codes used to denote platform identification, so you could have an A body Dodge and Plymouth, B dody Charger, Super Bee, Road Runner, GTX, things like that. This lettering system still appears to be in use today, which is how a Chrylser 300C is on the same platform ( I think this is the key), along with the Dodge charger Sedan and Magnum.

Hi, I just saw this.
 
My question really is, if the A,B,C... designations came from corporate, where did they use them.  I've never seen anything official other than the car line letter codes, which are different, and more specific.
 
Where the A,B,C designations simply used for internal memos, or what?

I think the A,B,C,E etc designations did originate internally as
corporate shorthand for platforms, there's a dude Bill on
forwardlook.net  who used to work for Chrysler and would know for
sure.



I also think I remember him saying those letter designations were used
internally starting in 1965, and that the 60-64 unibody full size
cars:  60/61 (only) Fury, 62-64 Dodge 880, Newports etc were not
called C bodies at the time, but for all intents and purposes WERE the
same C-platform as the 65 and later Fury, Polara, Newport, NYer, though
not labelled as such.

Used by the engineers and designers to denote a platform. A platform is the designation given to a given set of hard points in which to build a vehicle, hard points determines where the A, B, C pillars, windhield, wheel wells, radiator support, are in relation to the wheel base itself, and the design of the suspension. The A, B, and C have different suspension designs, as in size of components, length of torsion bars, wheel base and width. E body uses the B body style front suspension, not sure about torsion bar length, but they are not as wide as the B or C body but still wider than an A body.  Before the letting codes, if you recall, P codes were used, like P16, D24, things like that.

Excellent allpar.com post Bob, and quite definitive. 67-on Imps are C bodies with modified front subframe and LOTS of sound deadening. I couldn't believe how much quieter our '69 LeBaron was vs the 72 Chrysler.
