See if you can locate a the December issue of Kit Car Builder magazine. This issue has an excellent article with photos of the cable driven windshield wiper setup. The cable is a special cable that has a fitting on it to attach to the ecentric mechanism in the wiper motor.
I have found a couple of excelent articles in this magazine since subscribing to it. There was a nice article on emergency brakes also. You can subscribe at
