These Performance Automatic hardened input shafts are custom-forged from 4340 non-twist steel. Quality, performance and great value make these hardened input shafts an essential component for anyone looking to raise their transmission to the next level. The early model C4 (1964–1969) used a .788-inch 24-spline input shaft, which was upgraded in 1970 to 26-spline and .839-inch. The upgrade also included a matching clutch hub of 26-spline. In 1971, Ford went to a .839-inch 26/24-spline input shaft, meaning the torque-converter side is 26-spline and the clutch hub is 24-spline.Models:PCE602.1003 - 24/24 spline 0.788-inch : 1964–1969 C4, C5, C6, C7, C8, C9PCE602.1002 - 26/26 spline 0.839-inch : 1970–1970 D0PCE602.1001 - 26/24 spline 0.839-inch : 1971–1979 D1, D2, D3, D4, D5, D6, D7, D8, D9PCE602.1008 - Early to Late Converter: 26 spline 0.839-inch to 24 spline 0.
