The reason the part is $50 bucks is because Soft Seal has a monopoly. Every other manufacture has been driven out of business by Wal Mart shoppers that want the cheapest part, not the best part or even a good part but one purchased solely based upon price.
Moog and Firestone Rubber used to make the part but stopped because they have to pay a living wage and comply with safety and environmental issues as a US manufacturer. If China, or India or Malaysia or Pakistan hasn't made your part yet complain to Xi Jinping (China), Pranab Mukherjee (India), Imran Ahmed Khan Niazi (Pakistan), or Perdana Menteri (Malaysia) would love to make another part for export to America. As far as that goes all of the Stans in the east are looking to take away American jobs
