If I didn't have to try and find time to ship it , I have a spare ralley rim . If someones going that way I could send it with them .
The nut/bolt is actually a bent pice of steel with threads on one end and a cone .... looks like a round lug nut in the end of the stock . And there is a big washer with a lip that captures the center of the wheel . Don't have any spares for that .
But you could always use a big washer and a nut from a hardware store in a pinch . Maybe even weld a handle to the nut to kinda emulate stock .
