I just did a quick search and found one of the guys re-building head light motors. His website info is pasted below.

Some of you know that I rebuild/restore the headlight motors for 66 & 67 Chargers. What you may not know is that I am expanding my services to include wiper, window, and 70^ headlight motors. My website is www.headlightmotorman.web.officelive.com Check it out and let me know what you think.
