Wheel mounts broke

The parts I received were similar but not an exact match to the original part. The original part is no longer produced. The original part used threaded screws to mount the assembly to the dishwasher body. The replacement part had and open "shaft" that was approx 3 times the size of the threaded screw used previously. My solution for this change: I purchased 8-32x1" stainless steel carriage bolts with matching nut. The head of the bolt fit nicely within the opening of the wheel mount. I salvaged the rubber washers out of the old parts and used them for reassembly. Inconvenient, but problem solved.
