Scott, they are available in Germany, so any US dealer can get them if they try hard enough. Or you can order from speed-autoteile.com and have them shipped over. Not cheap though, both through 'Speed will be about $300 USD shipped. No idea what pricing would be via MBNA. Here's the link for proof of availability:
