Early 833 ID???

Just curious, how can you tell by looking at the input shaft that it has the 3.09 first?

Hey guys. I have a few questions myself, I’m trying to identify it. I have a 68 Barracuda and so I need to know if the one I’m looking to buy is for an A body before I buy it. Let me attach some pictures.
Numbers I see are C 95638 U
And on the other side I was told the numbers are 95838 or 95839 U

If any one can help me decode or identify that would be great.
