I think
@Dano1973 is right that 1972 and 1973 should be the same. My expectation is that is emissions-related.

Looking at Herb's, starting in 1971, they have two
sets of two-piece
lines for C-bodies (note that the wheelbase's are different, yet the lines are listed for "c-bodies"). That's metal 4 pieces in total (abstracting from the pump-to-carb lines). For the 1973 Chryslers, the first one is a front-to-rear 5/16" 2-lines set, the second is a 1/4" return line (also in 2 pieces).
@71Polara383 took the following photos of the lines on Ming, my 1973 Chrysler.

I would love to hear from fellow 1972-1973 Chrysler owners about the clips that they use, as the R clips from earlier years to do not look like the correct set here.

Inline Tube has the following double-R clips:
Fuel Line Clip Double R Style 1/4" & 5/16" -- sold out...
Fuel Line Clip Double R Style 1/4" & 3/8"
Fuel Line Clip 5/16" & 5/16" Double R Style Silver Zinc
Thoughts? As for the rubber fuel lines and clips, Inline Tube has a
1/4" set (rubber line and 4 red clips) but is out of the 5/16" set, while Mancini has a
5/16" set (rubber line with 4 black clips) listed for a 'Cuda. Here are some pics, let me know if this matches what you see on your cars?
