Flamin'69Cuda

Does anyone know where I might find a complete windshield wiper assembly? Does it have to come from a '67-'69 Cuda or just another A-Body of those years? I need everything;wiper arms, motor,& linkage/ transmission parts under dash. I bought a '69 Resto-Mod with a360 Magnum Crate Motor, Gear Vendors Under/Overdrive & all AutoMeter Gauges (9) on the dash. There are chrome knobs on the splines where the arms should be and that's all !!!
