Wiper switch compatability?

Nice!
Feel free to borrow from the discussion I linked to earlier, and the thread that in turn links to.
In it we try to cover the wiring, wiper motor assemblies, and switches for four variations we identified for 1967.
The 'white plate' motor seems to be a holdover from 1966.
Maybe in a B-body. All the '66 A-bodies have the interior mounted wiper motor that doesn't have that plate.
