OK, now I think I can post all of the attachments to illustrate why I'm confused about this and why it matters to me. I'm trying to get the front suspension/brakes correct for the '73 duster. I don't have a Plymouth Service Manual, but I do have the downloaded version of the Dodge Manual. The front suspensions should be the same for the Duster and the Dart, so I want to follow the instructions for the Dart in the manual.
In the intro section of the manual, there is a carline identifier. Here it is.

Caline designations are L(Dart), J (Challenger), W (Coronet/Charger), and D (Polara/Monaco). So far, so good.
Now, I go to the Torsion Bar section. This is it.

This section purports to cover P,D,C, Y and R carlines. There are
NO P,C, Y or R carlines in the carline table above. Moreover, there is
no instruction for torsion bars for the Dart (L carline).
Aside from the confusion in the service procedures due to this, I have another reason for wanting to nail this down. Go to the Brakes Division of the Service Manual section here.

At the top of this page, I want to find the correct front rotor thickness, minimum thickness, runout, etc for the Duster/Dart. Note that the manual gives specs for "R-W" and "B-J" carlines and "all except R-W and B-J". What the hell is R-W and B-J???
Maybe I'm just dense and my novice status is on display, but this make no sense to me.
