Yep, they are ion the stock springs. Kinda hard to see when your springs have been on the car for many years. The shop overlooked them. After I had clunking for one day, I looked at the stock springs carefully. You can see that there is some tubing which goes around the coils. They come off easily, and will fit on your aftermarket springs securely. I went back the very next day, and no more clunks ever again.

Now camber kit clunks are another issue...
