I've got a 97 with the exact same issue, glad to read somebody who found the problem, saves me a lot of time where did you find the clips and how'd you put them on? thanks!

 

Glad you figured it out.. I chased down an annoying sound like that on my first gen a couple years back, turned out the rubber bushings on the calipers wore out and fell out.. so they were loose and just ticking around..
