For Chevrolet, it was a 1 year only axle, only used on Positraction equiped 1/2 tons, GMC used it '55-'59, though some GMCs did use the Chevrolet axle. Unfortunatly, the cable are specific to that axle, I don't beleive later Chevrolet cables will work. Ed might have the best answer, having them custom built to fit rather than searcing for rare/obsolete originals.
