I chickened out and bought NOS ones on the last ones I did. You know they should fit right and were old school USA made as well.

For the install I have always been able to turn them in by hand with a breaker bar followed by a torque wrench. I like being able to feel by hand what is going on as far as binding up or not.

One set I did that was a little too loose I took a crescent wrench and gently bent the control arm opening inward on itself by going around the outside many times over. I was able to get the torque I needed so it did work.
