Caliper Abutment Clips

OK guys, since I redid my front brakes on my 00' I've been getting some clunking noises that goes away when I touch the brakes. It's not the U-joints, because I replaced those about 500 miles ago. It's also not the wheel bearing hub assembly (I replaced that to).

In the box with my new pads were some caliper abutment clips. "to reduce
the clearance between disc pad (steel locating surface) and the guide
rails". The old ones didn't have them, but I tried to install them anyway.
Couldn't get them to go on with the clips in there so I figured everything
was probably OK. Starting getting the noise, and noticed on the
instructions that read "symptoms of worn anchor plate guide rails include:
brake noise caused by chatter, clunking or clicking". My guess is I just
found my problem.

Any thoughts, I'm guessing I just need to install the clips, although I have
no way to measure the clearance, which is supposed to be "a minimum of .10
inch and maximum of .015 inch).
 
If your guide rails do not have a grove worn in them by the brake pads you shouldn,t need to reduce the clearence.
If you must check then buy a cheap feeler guage and cut it to fit.
You did clean and lube the locating pins ? Turn the discs? Or replace with new discs?

I pulled the wheel last night, there's no grove, everything looks fine. I shouldn't need the clips.

Not sure what the locating pins are. Guess I better get the Haynes manual out. Maybe I missed a step.
