Where can I find them? I remember seeing a thread with them about a year or more ago...

They are little "inserts" for lack of a better word, that go in your drag link. You drill the drag link out to the size of the insert, and then the insert is tapered on the inside to accept the ball joints, and then the insert slides in the drag link, making it easy to get the drag link on and off the car. Quite handy if the drag link goes through your pan, or headers...

Thanks!
