I'm wanting to put trim rings on a set 1985-87 SS III 15" wheels. If the rings for the mid 70s 15" Super Stock wheels would work, that is what I would want to use. The reason I question if this will work is that there is an extra step on the rim of the later wheels. I'm wondering if that will prevent the trim from going on all of the way. So may of these wheels have rust in the outer rim portion of the wheel. I'm thinking someone has tried this.
