Yup. That's them.I have been trying to figure out what type my LCAs are on my 95 8 lug K2500. Do these pictures look like the second option you described as, "A newer version of the stamped arm apparently uses a permanently-attached (welded?) forged end with a press-in ball joint. I've never seen one of these in person."
I've still never seen a set of those in person.
