if you are referring to the backing plates offered by Ed Miller I still have them and will sell them to you if you'd like... along with a set of used rear calipers.
I decided not to use them on my car after all because the shock absorbers have to be moved inboard with a bracket like the one that comes with the baer kit. I decided I wanted to keep the factory design rather than alter it. nothing wrong with relocating the shocks, it's just a preference thing for me.
