Hey, Agent_S13. I got D-speed Sidemarker from www.jspec.com about several month ago. They used to sell it but it quickly sold out. Paid 90 bucks. Pretty expensive but it cost 6,800 yen in Japan(about 70 bucks). They might sell it again. Send e-mail to them. And here is official site in Japan

Or just try ML320's sidemarker. I think it's fine and much cheaper. I got Dspeed because I didn't want shave and cut stuff.
