Where to get 16.5" throttle cable

I had this issue when I went to a 4-bbl from a 1-bbl on the truck. I needed a cable that was a LOT shorter. I figured out what length I needed, then went to Rock Auto and started punching in various years/model/engine info till I found one that fit. I think I wound up with some kind of Volare cable but it fits and works fine. A bit of busywork to find the right one but it was effective.
