The wiper arms are stripped so badly, the wiper no longer moves. I took
the arm off and found the post (not the wiper arm) is stripped pretty
smoothly. The grooves are barely noticable. Also, the wiper arm
(receiver) is stripped so badly it "seats" so far down on the post,
it's rubbing the metal supporting the post.

I figure, I need a new wiper arm as well as post. Can you replace just
the post or am I looking at the whole (motor) assembly? Is a salvage
yard a good place to get replacements? I would hate to see what Ford
would charge.

TIA!
