Need V8 904 Core or Case in So Cal or So Nevada

I've got a really nice 904 out of my old '67 barracuda with a 273 commando, so it's probably got certain special parts (governor springs or?) . I converted the car to a 4-speed and this trans has less than 100K original miles on it, and I'm pretty sure it's never been opened up/rebuilt. It comes with the torque converter also. $250
