Got a Permco 257 pump and need to know if this drive shaft will match up to an SAE B spline configuration, that right?

SAE B spline is exactly the mount spec on this shaft, so it pairs with Permco 257 units built to that standard. If your pump is spec'd for SAE B, you're looking at the correct replacement.
