I have this old wiper switch I removed from a sixties full size Olds sometime in the last 6 or 8 years. It would have been probably between 63 and 67. I'm sure it worked. I have the matching headlight switch **** as well, but can't sell them as I don't know what year I took them from. The wiper switch bezel says 588804 on it. If anyone could help me identify these, I would be greatful (even more greatful if you knew someone who needed them) !!

 

Looks like 64 to me.
