Do they make Baby Moons like this?

Not sure if this is the best forum to post this in but here it goes.

Do they make Baby Moon caps that clip onto the lug nuts like those caps on modern Fords do? You know, like on cop cars and some F-150s I know have the lug nut center cap that clips onto the lug nuts.

The reason is I have these American Racing chrome rims that are essentially smoothies after you take the wire spokes, centering post and other parts off of them. I don't like the look of the spokes on my old 49 Lincoln and I don't like how they rattle going down the road. They came with the car when we got it back into the family, someone else put them on there. Eventually I will put American Racing vintage smoothies with white walls on later but for now due to budget and the fact is this car will be part of my wedding on the 31st of July, I have to deal with them so does anyone know of baby moons that clip on?

There is no ridge for the traditional style to clip onto, not like the steelies that they are meant for. Or does anyone know where to get a hold of come cop car moons that clip onto the lug nuts?
