Many people do not realize there is a difference between the 66 and 67 dash instrument panels. This is easy to confuse if you have not been shown or seen the difference. I will post a few pictures here so you can see that the 66 dash instrument panel has a much shallower recess for the wiper switch than the 67.

Hope this helps those who are wondering
