throttle cable length?

I had the same issue going from 1-bbl to 4-bbl on the slant in my truck. I measured what length would work, then went to Rock Auto and started going through cables for all kinds of Mopars. They list the length but only in each individual listing. The truck is an 82 but the cable was something very much different.

It's a time consuming process but it did turn out OK.
