Sorry no specific help here either but I can direct you to some. Try the website Autogeek.com (just google autogeek) they sell great products. But more important they have a forum section where you can ask a question and read posts already there about buffers. I believe they have on-line help (live chat) or at least you can certanly call and ask. They sell good stuff, I've bought from them before. And no, I have no personal interest in them either.
