I would take 2-3 sets of polised and 1-2 sets of brushed ones, but only if they are 100% correct, and somewhat reasonably priced.
The 14" rings are still available, part number is 2944424. They were priced around $30 each a few years ago, now they are over $100 each! What's the reason for such a huge price increase? I guess I shouldn't complain, at least they're still available.
