I'm tryin to fiure out what this is. I'm pretty sure it's not from the USA as it's hand written H50 coaster on it. I think thats a toyota van outside of USA. It's a 5 speed. I don't think those vans come as 4x4 though. To me it's almost like a strange H55F mated to a one piece case instead of a split case. It's 10 spline on the transmission input. Maybe it would bolt to a F or 2F engine? Thoughts?
