65 Coronet Throttle cable

Car is in the shop getting some upgrades, throttle cable broke. I researched threads here and online parts. Mancini has one as well as Summit and Jeg's, any recommendations from experience. What is the correct length? No, I can't just go out and measure it because the car is 80 miles away from me in Boulder City, the guy working on it called me and informed me of this.
So is the 24" cable long enough?

I’d contact Joe Suchy. [email protected] He’s in Indy right now, might be a few days before you get a reply.

Kramer Automotive also.
