Just as an aside, how well did these work for you. I was thinking of doing this to mine instead of dropping the 200+ for new arms.
Never installed them back on the Skylark after the inserts were welded in. I took the dry rotted bushings out when I sandblasted them and it took me a while to find someone that could press a new set in.... so instead I bought/installed a set of UMI trailing arms. I had the new bushings pressed in the old arms a few months later and since then they have been sitting in my basement. BTW, I did buy some repop control arms and my experience is that they are chinese junk. They may look close, but they do not fit properly and can be more headache than it's worth. My $.002. I am completely happy with the UMI set and was able to install a gm rear sway bar without shims. Very easy install.
