My fault. With repsect to the link I was only referring to '67.
Saw this

and looked in the '67 parts book (revision printed Jan 1968 )

So it seems like the above linkage parts are the same for 67 moodel year regardless of motor.
I don't fully trust the parts book on the wiper info because we've identified what? Four motors - switch setups on '67s?

here's what this parts book lists

Don't know what "Gear and Gasket pkg" refers to. Maybe its a replacement package including motor and pitman, or maybe an internal parts??
