Passion 4 Mopars????

I got a wiper motor from her about 5 years ago it was sent out fast and it looks and works great . I sent her a core for the 125.00 exchange I forgot about it for a few months then looked and I was never paid so I phone her up and she paid it the next day . I never cracked it open to see what's inside it could be all old parts I can't say .
