They stay on just fine, but they don't look like the originals, as they don't have the Cartier watermark, and they deteriorate in the weather rather quickly. I put a set (available from the dealers for $40 per pair) on my Black 81 in about 1994, and they are still on there, but they have a very cloudy look, and my car NEVER sits out in the desert sun for more than the duration of whatever trip it's on. The originals, which were still on my dear departed Blue 81, were still perfect in 2000, even though that car lived outside all its life in my same desert area, and had the oxidized paint to show it. I think the part number shows in the Brad's NOS auction mentioned the other day - look on the plastic envelope in the picture. The number in the parts book is probably the original crystal part number, so it won't do you any good.
