The factory originals are ceramic as you already know I'm sure & the replacement upgraded ones are metal. If one of the originals crack and throw a piece off - it can do some damage if your not lucky enough to have it blow through.
If any members here have already done the upgrade, they most likely will have a used one or more laying around with a little luck. Hopefully someone will chime in for you. Have as of yet not touched mine, so no help unfortunately..
