Can't be too difficult to draw your own. The 5 wheel bolts are on the standard 100mm pitch circle diameter and you can take the inner, outer and spiggot dia dimensions from your existing hub.
bear in mind the base of the spigot is not a square edge. Not sure of the radius, but would expect it to be of the order of 3-4mm, and you really should get it right for the wheels to not wobble at speed.
