Will a 1978 A833 4 speed out of a 78 power ram 4x4 truck work in my 73 chally, or is the tailshaft different? basically could I remove the 4 speed, take off the bellhousing and use it in my small block chally conversion? I have a 318 904 8 3/4 in the car right now and I am staying with the 318 and 8 3/4
