Kurt, if all else fails this place may be able to help. They have a huge parts inventory for some of the most rare fuel pumps, water pumps, carbs, etc. anywhere. If they don't have it Mike can build it. He's made parts from scratch for vehicles I've never heard of. If he can't find it or make it, it probably can't be found or made.
