Wiper pivot seal fabrication?
Here try this guy if you can't figure anything out
http://www.DetroitMuscleTechnologies.com. He seems like a great guy and it seems like I read in one of his ads that if he doesn't make it already and thinks there may be a market making it he will make the first customers for free if they send him an old one to use as a templet. Maybe it will work for you good luck Justin
