Mine broke also. Repaired by getting longer bolts and then a stack of washers that will fit in the narrow part of the top plate and then a bigger fender washer that will fit through the large part of the top plate. Finally it's held together with a nylon lock nut. I used a dremel to smooth out what was left of the plastic where it snapped. After assembling I put hot melt glue over it so it wouldn't scratch the floor when I set it down.
