well neiter of those three are what it says, so what is it? It's code CC, it's got a 6 bolt allison convertor and a fixed yoke. It's never been dug into so nobody knows what the gear type is.

I know the 77 is the year and 4645 is the serial number, but what does CC come up as far as either 475 or 400, and what does 547 mean? If it's may 4th, would that be logical if the engine was jan 14th for it to be a numbers matching unit?
