I've only seen the hairpin clip but then I have not seen them all.
I have also seen original examples with nothing.
Plus another print shows different end tabs
Mechanics hated shaker set-ups because of the burden of removing everything to work on carb(s).
I remember one mechanic told me those kinds of things were the first to be tossed figuring the screws are holding the cable tightly.
As for the cable ends I've seen two different long cable ends, notched end and not, and then there are the two different repro versions.
As for short cable, here is an NOS one on the top verses repro.
Note the end differences and taper on the original... plus, any short originals I have seen always had the ribbing as seen in the original with script.
