Mag wheel covers
They only fit the 14x5.5J wheels. We had a set restored in 2007 and is cost us $3500, but they had to be perfect. There was a guy who was going to reproduce the outer ring, but I don't think it ever happened. I have had several sets, sold and NOS set a couple years ago for $2K. Here is a pic of the restored one's. I don't know anyone restoring those right now...
