Where to get steel wheel centre caps?

[xr2racer]

I've got a set of 15" steels for winter, annoys me that the hub gets exposed and rusty. Anyone know where I can get some centre caps preferably in black?

I've got a pair for sale. Or maybe even 4, steel centre caps. No idea if they would fit your wheels though.

They fit over an OZ F1 though. And are black metal.

Let me know via pm if they could be any use to you.
