Cable type gas pedal for early A

Back in the early to mid 70s,I put a cable pedal on my 65 Valiant when I put a 340 in it. I don't recall what I used but I was just a 20ish yr old kid with no resources, so it must not have been too complicated. I remember well taking off the slanty stuff, but nada on the cable stuff. I'll guess something off a Demon or Duster.
If the pedal doesn't sit right, maybe you can bend the arm. Take the plastic off, and use a lil heat and voila. Three of my most-used tools are my hammer and my vise and my torch. I use them on everything lol.
