67 Barracuda Throttle Cable

Looking to replace my throttle cable on my 67 Barracuda Convertible, 273 Commando, with the original 4 barrel carb, Automatic trans. I have ordered from PG Classics and after two cables that didn't match mine I'm at a loss where to turn to next. As you can see from the photo below from the firewall to the attachment point on the bracket on the head its about 13" and about 19" overall length. Any insight on where I might be able to get one?
