It appears that the cam is only $2.45 from the dealer PN 025 133 136A and the
washer that is supposed to be changed with it is 025 133 188 $.58
I am going to check with the local dealer to see if these parts are still
available (sometimes they are in the book but NLA) and I will buy 10 or so,
the next time I sell a switch I will sell the cam and washer with it.  I'll
let you know what I find out.

Thanks,
Ken Wilford
