The connector link, or control link, or whatever you want to call it, had rusted away, on a project car that I work on, when I get the energy. No replacements seemed to be available anywhere, so I found a manufacturer of the ball studs with the correct metric thread...had to buy a minimum quantity. Then bought an equal number of metric threaded studs of about the right length (You might have to knock a quarter inch or so, off). Sold a few sets on EBay, but have a few left, in anyone needs one. Not a real hot item, I realize....I'm just sayin'. This is the link that goes between the compressor control/delay switch (In the rear), and the upper rear control arm. Also, I'm lookin' for a replacement for the clip that holds the short fuel return pipe into the fuel pressure regulator.
