Ang, the only stopper mandrel I have is the one I bought from BB since I got all my stoppers from him. This means that I cannot answer your question. However, the stoppers in question use a standard size. Unless you need the bushing that comes with the mandrel, this means you can take a stopper bottom to Lowe's, etc. and buy a bolt with the same threads and make your own mandrel. Just make sure you get a bolt with the threaded part no longer than 3/4" and still have about 2" of smooth metal cylinder behind the threads. Just cut the hex head off and you're in business. Make sense? Oh, and if you do want a bushing, you can turn your own to fit using Corian, or anything suitable. When you gouge it up, turn another.
