I have hadone missing for a while now too. I tried a dealer a while back and they tld me I would have to buy the whole horn button assembly for like $90 LOL. Needless to say I sill have a missing horn button. would say your best bet is to try and get lucky at a junkyard (I have hd no luck here in Columbus Ohio for years now looking on and off) or just find a nice aftermarket wheel from Grant, Momo, or Flaming River. That is probably what I will end up doing if my mission to find a S197 wheel and adapt it to my Fox fails.
