The upper cable came off a 79 Volare from a junkyard. The lower cable came from Byron Fettig, who owns a MOPAR parts company called The Dakota Connection. He has access to an amazing number of Mopar parts vehicles and has many times come through with rare parts for me. When I called, he had several lengths of lower cruise control cables available. I bought one and it worked perfectly. He can be reached at (710) 222-4362. Best to call after 5 PM. If all else fails, there are places online that'll make a custom one for you. Just do a Google search and you'll find them. Best of luck with your wife's Duster!
