Not the metal that comes riveted onto the pad, but the steel guides that basically just wrap around the soft cast aluminum.
I bought some that sounded and looked right, but ended up not being the right size. It's not a huge pain to take a tire and caliper off to check, but it does take about 45min by the time I do it all and clean up, so I was hoping someone had a part number for me.
The dealership wanted to sell me a whole caliper...
