1973 Swinger Trim Options?

I was curious what the trim options that separated the price classes for the Dart Swinger.

I know that the LL is for the Swinger Special that was made in Ontario, but with a 318 under the hood I can’t tell what would differentiate it from an LH.

On a similar note, is there anywhere there’s a list of the full options that someone could order this car with?
