Best way to find original 240 wheel covers (hubcaps) for a reasonable price?

My 240 came into my possession with only two wheel covers, so my idiot self decided that rather than Harvey Dent my car, I tossed them. I thought it looked slick at first but as a 240 owner I'm learning that the classic clean look is best. Most eBay listings are ridiculously overpriced or don't have a set of 4. Most junkyards in my state don't have 240s. Anybody know of an online seller or has a buddy with 4 collecting dust?
