If I remember correctly mine is 52". I absolutely love Mark Williams products and have many of their rear end components. When I called about a driveshaft a few years ago they told me I needed carbon fiber. WHAT! This is a mid 11 second bracket car. I think the charts are VERY conservative as far as critical speed ratings. I don't have room for a 4" shaft. I ended buying from a friend with a similar car a Strange 3" chrome moly shaft. No vibrations. A friend with an identical car to mine is using a 3 1/2" aluminum shaft as well and this car is at 10 flat. We both run Jerico's.
