[DeTomaso] Seat Slide Rattles

I was told by my mechanic that the original nylon(?) slides inside my seat rails had disintegrated and they were replaced with the solid brass rollers. I can clearly hear them slide back and forth on the rails when I start and stop. I placed a thick 3M tape on the rails and the sound has lessened, but still can be heard. Is there a fix for this? Please EMAIL me because it is easier for me to follow email than this format. Thanks in advance.
