"You might find a good used one - make sure you ask if the floating bushings just float (you do not want them wobbling)."

Most steering knuckles that have been sent to me were no good (very loose bushings - a very common malady). Some of the sellers gave all my money back. None of them asked me to send one back (they said to throw it away). Try to find a seller who knows what to check-for and will guarantee the knuckle is useable.
