For fastening the cable to the car, there are three clips that hold the main cable to the frame. As far as I know they're still available. Part # is in picture and you need to order 3. About $6 each. And yes they do rust away, leaving the cable to flop around under the car. If the clip is gone, you should see a hole where they were. I don't have pics, but here are the approximate locations. My memory is a little vague so this is the best I can recall but you should be able to follow the cable to find the holes:
1. In the floor pan (or maybe in the little rail) a couple of feet back from the little bracket where the main cable hooks up to the front (pedal) cable.
2. On the side of the inner fender forward of the wheel well where the cable starts to snake up towards the top of the subframe. Just follow the cable up and you should find the hole about a foot or so up.
3. In the floor pan above the subframe rear of the axles. There's a small hole with larger holes on either side. You want the small hole. This one's a bitch because it's hard to reach and is filled with expanding foam on the opposite (inside) of the car. Mine had the rusty remains of the old clip inside and it took a while to dig it out with a screwdriver so the new clip would go in.
Also, the adjuster assembly came from the factory zip-tied to the sway bar to keep it from rattling around. Pretty cheesy but I guess it works.
Oh yeah, here's a parts diagram. The first one is where the "F" is, the second right behind it and the third is "G", although it's further back than the G is pointing.
