You can get a notched cross pin (not sure if a 28 spline will work on a 31 spline) but you don't need to. Most people, my self included, slightly grind one tooth on the ring gear to allow enough clearance to install the stock cross pin. I know it sounds crazy to take a grinder to your brand new gear set but it works link a charm, is cheaper thenbuying a new cross pin, and doesn't significantly reduce the strength one bit.
