identifying 4-speed transmission

I've got what should be an a-body 833 4-speed transmission, and I'm trying to identify it. The number on the tail shaft is 96709, or 967D9. There is also a separate "C". Does anyone know what this is ? Year, gearing, spline, anything ?? I think it came from a 1966, 273 barracuda, but not sure, and what would it match up to as far as engines go ?
