I'm trying to find a lower ball joint for an '88 Trail Boss 4x4. The ball joint looks like a tie rod end and Polaris claims that they are no longer available. I found an application in Parts Unlimited but when the ball joint arrived it was the "newer" style and incorrect. After visiting with the tech people at Parts Unlimited, they conceded that they do not have the correct part available. I've looked online and can't seem to find a new replacement anywhere. Any thoughts or direction?
