Rare hard to find parts

You'll say that, until the day that the ball joint/tie rod stud decides to break loose when you have that nut halfway off, and just sits there spinning round and round. Then it becomes a real PITA. You'll either have to figure out a way to try and hold the stud from turning (nearly impossible), or cut the nut in half. Been there done that when I was pulling some discs off my '76 parts car.
