Someone had to custom make those adapters to use pan wheels on the Dom/Yok axles. I don't know why you would want to, those tires on a Dom would give you an unusable and non-adjustable ride height, and there are plenty of foam tires available for Dominators.
The inside mounting diameter of a Dominator wheel is a LOT smaller than the on road wheel, and the bolt holes are not the same. Those adapters are not the same.
