Where do I get LH thread 7/16"x20 3/4" shoulder Mag Lug Nuts!

Hey thanks guys. I've checked napa, they said they don't carry any left hand thread lug nuts in 7/16. I've been looking on ebay this afternoon and havent come across any yet.

I put in a call to the Lug Nut King (www.lugnutking.com) as he has some listed on his site, but haven't heard back yet.

Any other ideas?
