I actually called Cyberdyne and the Turbo Buick dash has been discontinued. However, I was told by a friend that the sending units were made by Stewart Warner. My friend has a small business and was considering being a distributer for the Turbo Buick Dashes.
Yes the buick dashes have been discontinued I believe since 97 or 98. That is why I am stocking up! However, they offer lifetime warranties so all you have to do is send it to them and they will try to fix it if there is ever a problem. All the sending units are available at Jegs. In fact, if you go to Jegs and type each part number that is on the cyberdyne parts list, they all come up. Might order an extra set of senders just to be safe.
