I would suggest looking into putting a cable style throttle set-up off a newer truck if you want to stay with that carb, then fabricating a bracket for the cable to the engine.

Try to find a fairly long cable, as it has to change directions as well. I'd get out the old tape measure, figure out how much engine bay cable you need then go to the u-pull-it.

I believe you can retro-fit from 71/72-mid nineties or even higher. Just make sure the engine bay side is long enough.

Minor fabrication required.
