Actually in the true spirit of diversity, all cables are considered equal regardless of length, stickiness, kinks, and what model year they came from. Discriminating against any one would not be considered politically correct. Now whether or not you can use a choke cable from a 73 on a 70 is a different matter.
I recently discovered that there is a difference. Luggnut73 has choke cables that exit to the engine compartment from the right hand side of the heater box, and then cross over the top of the engine via a bracket there. My 71 and the 72 parts car I have don't do this. On both of them the cables exit on the left of the heater box pretty much in line with the carburators.
Since the basic function of the choke cable is to pull a mechanism on the carburator, I would say that as long as you can get the choke lever housing to fit into your console, and that the cable you will be using won't require a massive curve put into it, or be so short that you won't be able to install the console, or have kinks in it which make it easy to snap off the choke handle, then go for it.
Just be sure that when you get rid of your old choke cable you don't imply that it's due to age, appearance or model year it came from, but rather that it's due to actual job performance and be sure that you have it documented so as to avoid a lawsuit.
Thanks for the mechanical, and legal advice for that matter.
So it sounds like the cables in the 70-72 are shorter than the later ones. I haven't looked in detail at the connection up at the carberators. If the cables are to long can they be cut to the correct length?
