I have a few drive-shafts, and took some dimensions for you. Maybe it'll help. I agree with the poster above. Put a sleeve on it, and save a few bucks, unless you're Donald Trump. The diameter of the yoke on a TH400 is almost 2", (1.885...approx.), and the diameter of the yoke on a TH350, early Muncie, P/G, and probably a 200 is almost exactly 1 1/2". So if you can find a sleeve, make sure the ID isn't 2", but more like 1, 1/2".
