I've got one in my garage that is in the same condition. I don't think they are made to be installed multiple times. I lost mine, completely came off, in traffic along with my power steering. That was a fun lane change/turn! I put the stocker back on for now.
Please do someone else a favor and DON"T re-sale it. If it doesn't work on your crank, it won't work on anyone else's.
