Wrong again 72blubberboo. They swivel. If you worked in engineering you know the many different terms for Heim Joints. That name came from a patent the Heim company held for a “Mechanical Joint”. And they all swivel.
Oh, my terminology is correct. I know the names that are used. But you are the guy that installed them wrong on your Challenger, because you don’t know the axis thru the ball swivels and needs to be as close to 90 degrees as possible through its motion.
You can unpurse your lips now and take your hand off your hip before your mascara starts to run.
