I'll second 3B, as it looks like what's in my 52 Chevrolet 1700, and the Canadian maintenance manual refers to it as Eaton 2 speed. Front axle though I'd have to look up. Surprised yours is 5 bolt though. I thought most of the Canadian builds were 6 bolt like mine, I'll look that up too. Is it possible hubs were changed at some point?
