Tom,
You should have two thin-walled non-threaded aluminu= m bushings followed by a steel nut plate.  If it looks like there= are threads cut into the aluminum bushing, then these were likely cut by t= he bolt threads during assembly or disassembly with some misalignment or si= de load on the bolt.
